I really wanted to love this place after seeing all of the glowing reviews, but what I found on a Saturday morning was a generic middle American coffee shop. Certainly not a bad breakfast option, but not worth a long walk from your hotel, either (if you are at Riviera or Circus Circus, though, check it out). Omelets are huge but filled with too much cheap American cheese, hash browns were rather hard and unappetizing. Maybe I caught them on a bad day...
I liked the blue and purple lighting and the 70's-style round booths. Waitresses wore "Hawaiian truck stop" floral print dresses and were exceptionally nice and attentive. Much better service than the average 24-hour hotel restaurant.
Can't comment on the dinner menu or late night experience - I'll have to go back and try it. Overall I liked the place, and would be more likely to return soon if it weren't a little out of my way.
