Mr. Charlie’s TMS: What’s Vegetarian Editorial Review

Mr. Charlie’s is the all-vegan answer to McDonald’s, and it sits directly across the street from one at 432 Sutter Street in Union Square. Every single item on the menu is plant-based, the kitchen handles no animal products, and the whole concept runs on a cheerful, tongue-in-cheek premise: what if the fast food you grew up eating was made entirely from plants? If you’re vegetarian or vegan and craving that nostalgic fast-food experience, this is the closest you’ll get.

What’s vegan and vegetarian at Mr. Charlie’s

Everything. That’s the short answer. Mr. Charlie’s operates as a fully vegan kitchen, so there’s no picking through a menu trying to find safe options. You won’t find dairy, eggs, or meat anywhere in the building. The menu includes plant-based burgers, nuggets, fries, tots, soft-serve ice cream, and combo meals they call “Frowny Meals” (a clear nod to Happy Meals). The allergen note on their nutrition page does flag wheat, soy, and soybean oil as common ingredients, so it’s not gluten-free territory, but it’s unambiguously vegetarian and vegan.

Signature dishes to order

Start with the Not a Cheeseburger or the Mr. Chuck. The Not a Cheeseburger is the plant-based take on a classic single with pickles, onion, ketchup, mustard, and vegan cheese. The Mr. Chuck doubles up the patties and adds signature sauce and lettuce. Reviewers consistently call out the burger patty as the strongest item on the menu, noting the texture and flavor genuinely echo the McDonald’s experience from memory.

The Not a Chicken Sandwich uses a Tindle plant-based patty with lettuce and vegan mayo, and it’s worth ordering if you want something with a little more substance. On the side, the shoestring fries hold up well. Finish with the Mr. FluffHead dairy-free soft-serve if you want to go all the way.

How to order

Mr. Charlie’s keeps it simple. Walk in, order at the counter, and you’re usually looking at food in under 10 minutes. The SF location is open daily starting at 9am, which makes it an option for a late breakfast or early lunch too (the Mr. Muffin breakfast sandwich with vegan egg and cheese is available in the morning). If you don’t want to go in person, DoorDash and Uber Eats both deliver from this location. No reservations, no waitlist, no fuss. It’s fast food, done vegan.

There are six sauce options including a jalapeño cilantro sauce, chipotle, and BBQ. The green sauce gets good marks from regulars, so it’s worth asking for a side when you order fries.

What to watch out for

A few things worth knowing before you go. First, there’s no public restroom available for customers at the SF location, which reviewers mention pretty regularly. Plan accordingly. Second, the nuggets get mixed reviews. Some people love the texture; others find it a little off-putting if you’re not used to plant-based takes on chicken nuggets. They’re not bad, but the burger is the stronger order.

If you have a gluten allergy, Mr. Charlie’s isn’t the right call. Nearly every item contains wheat, and the restaurant doesn’t offer a dedicated gluten-free menu or flag specific items as safe for celiac diets. The cross-contamination risk is real here given how wheat-forward the kitchen is. Vegetarians and vegans without gluten concerns will be just fine.

Is Mr. Charlie’s worth it?

Yes, especially if you’re vegetarian or vegan and miss the fast-food experience. The location alone is clever: you’re literally across the street from McDonald’s. The food quality clears the bar for what it’s trying to be, the vibe is fun, and the staff gets consistently high marks for being friendly. You’re not going to find a more approachable or casual all-vegan fast-food spot in San Francisco.

Mr. Charlie’s has grown to four locations since co-founders Taylor McKinnon and Aaron Haxton launched in Hollywood in 2022. The SF spot opened in January 2023 and has held up well. With franchise deals signed and more locations coming in 2026, this one’s not going anywhere. If you want a quick, fully vegan meal in Union Square that doesn’t ask you to compromise on taste or convenience, Mr. Charlie’s delivers.
