This is a 24/7 diner-style joint inside of SLS, so if you are hungry at any odd hours, chances are you will end up here. The plus side is they have gigantic portions -- great for when you're hung over, but if you don't want to waste any food, you should probably share an entrée with a friend.
On the other hand, the food is quite greasy and generic. The Mexican-inspired entrées lack zing, while the American brunch items feel like something I could get at any average Joe's diner. The prices do reflect the portion size, but they are still a bit high comparing to what you can get outside of the hotel. Guess you are always paying a little extra for the location ;)
Service is a downside. I know it's really busy here during brunch hours, but we hardly ever saw our servers and the turnover rate might have been slow as a result (slow to get our bill etc). I can't blame a specific server because it happened multiple times on multiple days.
