I had the lunch special this week at Estiatorio Milos in the Cosmopolitan. What a great deal!!!
You get three courses for $20.11, though there are a couple of upcharge options. My appetizer was one of those options, an extra ten dollars for char broiled octopus. My main was lavraki (sea bass) with horta (similar to spinach). For dessert, karidopita (walnut cake).
The lavraki, in particular, was outstanding...one of the best fishes I've had.
Service was excellent and the room is very attractive. I believe the lunch special is usually on the patio but there was a group out there so I was served at a banquette in the dining room.
I strongly suggest you take advantage of this deal.
