My wife and I came here one day for lunch, and we were a little disappointed. First the outside design is fantastic, fire inside a window and the design of it was just so interesting.
One thing we didn't really like is that they seem to want to build up hype by creating a long line when there is no reason to. All the times we walked by (which was a lot because we were staying at Planet Hollywood) there was a long line, and the majority of the time the restaurant was basically empty and could have sat everyone in line.
As for the food it was not really the best, we both had a burger, though I don't remember which because they were both pretty bland and unimpressive. The truffle fries were really good, though at times a tad too salty.
The milkshakes were also a little different, instead of just a milkshake, they put custard on top of the milkshake, very different and I enjoyed that.
I would not recommend going here for a burger, there are a lot of other places around the strip that have better burgers.
