I had the cheesy with fries and no tomato in it and it’s so good and you definitely have to load up on the 21 sauce put it in my burger all that made it 21 times better awesome for dipping fries the service the waiter and was pretty funny and pretty nice and the atmosphere. OK good I will come here again if I can.

This is the best burger place i have ever been to. The food, service, and restaurant is amazing the burgers are also halal which makes is 10x better. Me and my family always come here after we finished climbing in a rock climbing place. So we gain back all the calories we burned in a few minutes but it is worth it because the burgers are that good.

My organization has used their catering services for a couple events and while the food is tasty however; for a group over 65+ we did not receive any cuttery, utensils or condiments for the food. And this is BOTH times we placed orders not well received at the office.
