Reviews for Mustard's Last Stand

06/21/2025 - Darren C.
My husband and I visited twice during our Boulder trip and loved the vegetarian options, especially the veggie dog with all the works and the tofu reuben. The fries are seriously tasty, and the atmosphere has this nostalgic, old-school vibe that makes grabbing a quick bite feel special. The staff were super friendly and knowledgeable, making the whole experience even better-I'm definitely coming back next time I'm around.

I love them. Can't believe the bad reviews. These guys especially have the best fries of anywhere!
I eat there once a week.

WORST $3.00 hot dogs i've had, I'll go to
7 eleven for a good $1.00 hot dog in the
future

I took my money back and ran out the door. The owner was abusive to his employees - in front of me and other customers. I have been eating at Mustard's for 30 years. There are too many other great restaurants in Boulder to patronize this creep.

Totally boulder! A great place for vegetarians and non-vegetarians alike. Has the best veggie burgers I've ever had and truly amazing fries.

Food's is ok, but not worth putting up with the owner.
