Hand's down the best burger I've had. Grilled to perfection I usually order it with only ketchup, mustard and pickle. I was super hungover so I really REALLY needed this burger to be good, did not disappoint! Put Burger Underground St Charles your list of inexpensive burger places to try before you die!

This burger was amazing! Smash burgers are to die for. The fries have some delicious seasoning and are skinny like McD cut. They were awesome. My burger had a delicious BBQ sauce, sharp cheddar cheese, bacon, lettuce, and tomato. I will definitely be ordering again soon!
