Ambiance is good and on the surface you expect to have a better than average burger given the price and the upscale feel of the place.
I've been there twice, and coincidentally the same things have happened both times:
The cashier didn't know how to input a make your own burger, with chili, egg, and grilled onions (even though everything is on their list of ingredients to make your own)
The cook forgot my chili
They were out of silverware
I asked for a side of mayo which they forgot.
The most recent time, the burger and flavor of the meat was good, but it was a sloppy mess. The 1/2 lb. patty dwarfed the bun, which was rendered useless. When I did finally find the lower half of the bun it was a soggy and greasy.
My fries were cold and underdone.
Something seemed off too, as if the kitchen was short-staffed or inexperienced, as I saw orders going back and the food runners seemed confused.
I still *may* go back but I'd rather go to in-n-out like others have pointed out (not Five Guys though, I'd still rather have this than any food from that pit).
