They've changed chefs since I ate at 150 Central Park on Oasis. At the time it was a multi-course tasting menu which I liked although my tablemate (Paul Motter of CruiseMates) felt it was not enough food to qualify as a full meal. Bear in mind this was the first revenue cruise for the ship and they oddly could not source the ingredients for a course which we were shorted.
It is otherwise like eating at Chops, with gracious service in a nice quiet atmosphere. Some of the wine selections can cause guests to choke. I recall they had wines that went for $1000 or more per bottle as well as more reasonable choices. I was feeling like a Rockefeller that night and ordered a glass of red wine that went for $50. I could not tell any difference between it and a more typical $10 glass.
