We visited Mama's on a friend's ecommendation and we weren't disappointed at all. We knew it was going to be pricey (16$ Mai Tai) but it was one of best evening dinners in all our travels.
The food quality was outstanding, service impeccable and ambiance was magical. We enjoyed our evening right from the complimentary valet parking to the outstanding views off the sea cliffs.
If you have the time, this is well worth checking out.
