Amazing Service from Khushi at Fat Bastard Burrito!
Khushi was absolutely fantastic during my visit! She greeted me with a warm smile, took my order with care, and made sure everything was just the way I wanted. Her positive attitude and friendly service made the whole experience even better. You can tell she truly cares about customers.

Thanks, Khushi, for the great service—you’re a star! 🌟 enjoyed my burrito, veggie bowl prepared by her.

I really liked their tequila lime chicken tacos, PACKED with flavor, also tried my brother’s fish tacos, also excellent. I normally don’t like whole tomatoes but I did not notice them at all. The only complaint I have is how empty it was in here, y’all better come and try something here.

Great customer service! and the store was clean. Their waffle fries is a must try. Loved the food and was greeted very nicely. It’s a must try. Will be going to this location from now on.
