I visited Five guys recently for the first time and I can see why they have opened so many locations in such a short period of time. Their menu is pretty basic, hamburgers and dogs and lots of free toppings to choose from. I had a double bacon cheeseburger with bbq sauce and onions.
The burger itself is nice and juicy and tasty, but I can't get past the cheese. It just tasted weird, like I dunno, it didn't belong with it. In N Out still has my vote on a better burger. One thing 5 guys does do better though is their fries. They are oh so good and well seasoned. Definitely better then any other burger place in my opinion.
Their drink machine is off the wall. I was taking my order to go so didn't get one but I couldn't resist checking out all the different options you can make up with anything from water to soda to powerade. Also while you wait they have peanuts you can munch on.
So for the burger with the weird cheese I give 3 stars because for the price I think a key ingredient like that should be of better quality.
