The pros definitely outweigh the cons, but let's start with the cons just because it's more fun.
1. The scary tweakers RIGHT outside. Real entertaining to watch through the windows at first, but I noticed a lot of children in the restaurant staring out there, and heard one say she was scared; so that's no fun for anybody. But, because that has nothing to do with Five Guys as a company, only their scary surroundings, I didn't take away any stars for that. I just wanted to mention it because I'd want someone to mention it to me. :)
2. I took away the star because there is something fundamentally wrong with the french fries. I know there's lots of mixed reviews in the commentary, but I can only speak for myself when I say that I did not enjoy them at all. Neither did my friend who joined me.
But there's lots of pros!
1. Super fast service. I think our food was ready in less than a couple minutes.
2. Lots of seating. Seating everywhere, I can't even imagine the place ever filling to capacity.
3. The burgers really are the shizzle. I had a bacon cheeseburger, and it was quite delicious. I think the buns are "butter buns" and the burgers are made right there when you order them so they're super fresh.
4. There's a pretty dope coke machine that distributes a plethora of teas, lemonades, sodas, you name it.
Not much else to say... it's a burger joint. :)
