When you go to Vegas there is a LOT of competition when it comes to places to eat. There are plenty of places that you can go and get a decent meal, but there is basically nowhere that you can go to have your waitress bust out in a full on 1950's rock song while you are dining!
You can actually view a bunch of videos on YouTube taken at Roxy's to give you a feel for what to expect, but you really have to go there to experience it in person:

Bottom line: Roxy's ROCKS! Prices were fair, food was very good, and the spontaneous singing was fantastic! Don't miss Roxy's!
