If you like burgers, you're in Vegas and you've already been to In-N-Out, definitely give Fatburger a try. Like In-N-Out the menu is simple yet tasty, but unlike the aforementioned burger mecca there are Banana shakes...awesome. Being open 24 hours can be a good or bad thing, depending on who you are and whom you might be scared to see at 2 a.m....but then that kind of applies to the whole Strip, doesn't it?
