Answer: nothing can be verified about Mandarin Express itself, because there is no Mandarin Express chain left to verify it against. There is no working brand website, no published menu, no nutrition guide and no allergen chart. But that is not the end of the answer — the operator that absorbed the concept, Leeann Chin, does publish a per-item allergen matrix with an explicit Vegan column, and five items on it are marked vegan. If you came here for usable data, that is where it is.
This page previously presented six dishes with menu-style descriptions, a nutrition table and an allergen statement, all attributed to a brand that publishes none of it. Those have been removed. What has now been added is the thing that was missing: somewhere real to send you.
The Correction: There Is No Website, So There Is No Nutrition Guide
The one sourcing claim this page originally made was: “They do have a nutrition guide chart available from their website and on-site.” It went on to attribute a seven-allergen statement to that chart.
Checked on 31 July 2026:
- mandarinexpress.com returns an HTTP 301 redirect to a BrandBucket listing — a marketplace page offering the domain name for sale. The same happens from the apex domain, from http and from the www host. Following the redirect produces a marketplace page, not restaurant content.
- mandarinexpress.us resolves and returns HTTP 200, but the entire response is 201 bytes: a page titled “Coming Soon page” whose only content is the sentence “Please come back later.” There is no menu, no nutrition data and no allergen chart on it, because there is nothing on it at all.
There is no nutrition guide on that website because there is no website. That claim, and the seven-allergen statement resting on it, have been removed.
Correction, 1 August 2026: this page stopped one step too early
An earlier version of this page ended at “the brand publishes nothing, full stop.” That was accurate about Mandarin Express and unhelpful about everything else. It also carried a supporting claim that turned out to be false: that the former parent, Leeann Chin, “publishes no allergen or vegan data.”
Leeann Chin publishes a great deal of it. We re-checked directly and parsed the tables ourselves.
Why it was missed the first time is worth saying out loud, because it is a real limitation of how these pages get researched. Leeann Chin’s allergen grid marks each cell with an image, not a letter or a word — the markup is <img alt="true">, repeated 328 times across the page. There is no text in any cell. Searching that page for the word “vegan” finds the column heading and nothing else, and the table reads as completely empty. It looks exactly like a brand that publishes an unfilled template. Only parsing the image tags row by row shows the marks are there. We got this wrong by searching for text instead of reading the table, and we are recording that rather than quietly fixing it.
What Leeann Chin Actually Publishes
Fetched 31 July 2026 from leeannchin.com/allergen-information (HTTP 200): seven tables — Appetizers, Salad And Dressings, Entrées, Rice And Noodles, Desserts, Beverages, Side Sauces — each with seventeen columns:
Milk · Egg · Peanuts · Fish · Shellfish · Soy · Wheat/Gluten · Gluten Free · Vegetarian · Tree Nuts · Vegan · Mushrooms · Corn Syrup · Corn · Tomato · Sesame · Food Coloring
That is the US Big-9 allergens plus a genuine, per-item Vegan column — which is more than most restaurant chains of any size publish. Five items carry the Vegan mark:
- Mixed Vegetables — marked Vegan, Vegetarian and Gluten Free, with no allergen marks.
- Steamed White Rice — marked Vegan, Vegetarian and Gluten Free, with no allergen marks.
- Steamed Brown Rice — marked Vegan, Vegetarian and Gluten Free, with no allergen marks.
- Firecracker Tofu SF — marked Vegan, and marked for Soy, Wheat/Gluten and Corn. See the anomaly below before relying on this one.
- Appetizer Sauce — marked Vegan and Vegetarian, and marked for Soy, Wheat/Gluten, Mushrooms and Corn.
Two things not to over-read. Nineteen further items are marked Vegetarian but not Vegan — Vegetable Fried Rice among them, which also carries an Egg mark. A vegetarian mark is not a vegan mark, and on this grid the brand distinguishes them itself. And fifteen items are marked Gluten Free, which is a separate question again.
The anomaly: Firecracker Tofu SF is marked Vegan but not Vegetarian on the live page — a combination that cannot be right, since anything vegan is by definition vegetarian. Leeann Chin’s own 2023 nutritional guide marks it as neither. We are not picking a side on which is correct; we are telling you the brand’s two documents disagree about that specific item, so it is the one to ask about rather than assume.
Leeann Chin’s Own Disclaimer, In Full
This governs everything above, and it is the most important paragraph on this page. From Leeann Chin’s nutritional guide PDF (Last-Modified: 22 January 2024, authored December 2023), verbatim:
“The FDA identifies major food allergens as Milk, Peanuts, Tree Nuts, Crustacean Shellfish, Soybeans and Wheat, as well as ingredients that contain protein derived from these foods. All of these food allergens are contained in our recipes. All of our foods are prepared in a common kitchen, therefore, allergens could be present in any dish. If you are allergic to these items listed, please use caution and your own judgment upon consumption. Leeann Chin is not a certified Vegan, Vegetarian, or Gluten Free kitchen.”
So: five items are marked vegan by the brand, in a shared kitchen the brand states is not a vegan one. Both halves of that are the brand’s own words, and neither cancels the other. What it means in practice is that the marks describe recipes, not the wok they are cooked in.
Leeann Chin also publishes a full nutrition table (HTTP 200 on the same date). One practical note: the “Download Nutritional Guide” button on the allergen page redirects to the nutrition web page rather than serving a PDF, so if you want the document itself, the working copy is the one dated January 2024 under the site’s /lac_admin/ asset path.
Leeann Chin’s ordering system, checked separately, is no help here: its per-item icons are only Gluten-Free, Spicy and “AsiaFit”, and that last one is a calorie marker — the printed legend defines it as “FULL FLAVOR UNDER 400 CALORIES PER SERVING”, not a dietary designation. There is no vegan or vegetarian field in that system at all. The allergen page is the source; nothing else is.
There Is Also No Single Chain
This page originally described Mandarin Express as a chain that “began in 1985 and now operates in 13 states with a few dozen locations.” None of that is currently supportable.
Pei Wei’s own site describes Mandarin Express in the past tense, verbatim: dishes from “the famous former Mandarin Express concept” were folded into a Pei Wei format “available in food-court-style locations across 13 states.” The thirteen-states figure this page attributed to Mandarin Express comes from that sentence, and in it, it describes Pei Wei — not Mandarin Express. The 1985 founding date and the location count appear in no source that could be found.
Restaurants trading under the name Mandarin Express do still exist — in Maryland, Louisiana, Arkansas, Tennessee, Mississippi and elsewhere — but they are unrelated independent businesses on unrelated domains, with different menus, and none publishes allergen data either. Nothing on this page is advice about any of them.
Why Pei Wei’s Data Is Not Used Here
Pei Wei publishes a full allergen grid and a nutrition table, including tofu entrees. It would be easy to borrow, and it would be wrong. Those are Pei Wei’s recipes in Pei Wei’s kitchens. The same caution applies to the Leeann Chin data above, and it is why that section names Leeann Chin in every sentence rather than presenting the marks as Mandarin Express facts. Five items are vegan on Leeann Chin’s menu. Nothing here says any Mandarin Express dish ever was.
What Else Was Removed
The six dishes this page listed — spring rolls, Chinese green beans, mixed vegetables, lo mein, fried rice and steamed rice — were presented with descriptions reading as though quoted from a menu. No Mandarin Express menu exists to quote. They have been removed, along with the specific assertion that “the sauces contain chicken stock,” which had no source at all.
The lo mein nutrition table has gone. Its figures — 10 oz, 370 calories, 13 g fat, 51 g carbs, 11 g protein — match a third-party calorie-tracking aggregator, not any brand document, and the column it was compared against belonged to a different chain entirely.
Roughly two-thirds of the previous version of this page was not about Mandarin Express: sections on tofu with nutrition figures attributed to a health website, on vegetables, on rice and noodles, on fortune cookies, and a promotional passage about a limited-time plant-based product at another chain, described as current five years after its release. Those have all been removed, as has a paragraph of undated filler and an unsourced historical opening.
The Bottom Line
There is no brand-level publisher for “Mandarin Express,” so there is no brand-level claim about it that can be sourced or checked — vegan or otherwise. If you are standing in front of a restaurant with that name on the sign, it is an independent business, and the only way to find out what is in the food is to ask the people cooking it.
If what you actually want is fast-casual Chinese food with published vegan marks, the successor operator is the place to look: Leeann Chin marks Mixed Vegetables, Steamed White Rice, Steamed Brown Rice, Appetizer Sauce and Firecracker Tofu SF as vegan, and states plainly that it is not a certified vegan kitchen. Both of those facts come from Leeann Chin, and you should carry both.
