A friend in the Milwaukee area always talks about Five Guys, so we had to try it. Went their on Saturday about 7:00. In short, the guy at the register was not the nicest. I hadn't been there before and was trying to figure out the menu. He said he would explain, but really didn't. Just said the regular burgers have two patties and the little burgers have one. He was kind of impatient and then to make it worse got my order wrong. (Left off a topping I chose from their rather long list). By the time I noticed I figured "whatever". It's sort of awkward standing around waiting for your order - their really isn't a good area except in front of the soda machine.
Good news is the food was rather tasty. Not the best burger I ever had, but pretty darn good. Fries could have been more crispy - but they were fresh with the skin on and tasted good. A bit expensive for the bad attitude worker, but decent food.
