(I was a tourist to Vegas and came with about 10 guys) \n\nDon't expect to get served if you come in at 4am.  We left because they didn't want to serve us.  Didn't take any order for drinks or food.  Didn't even bother to properly seat us.  Just grabbed the menus and placed it on the table without telling us to follow.  When we asked if we were suppose to be seated, he gave a light nod so it was hard to tell what he wanted us to do.  His communication skills was lacking as if he didn't want us there.   After 15 minutes of being ignored, we left.  I don't know what their problem was but if you're going to open a restaurant until 5:30 am in the morning, you should treat all guest like they are wanted there.  Don't be surprised if any of the other 10 guys from my group rates your restaurant with a 1 star.
