Located inside a big hotel complex (Marriott Marquis), this Mike Isabella Moroccan-Spanish restaurant is far better than you might be expecting. I had (parts of) six appetizers and every single one was excellent. The eggplant and the shrimp stood out, but they were closely clustered in quality. First-rate Moroccan bread, too. I suspect the question is not so much what to get, but when it will run out of gas and collapse into the “only somewhat above ordinary” category. Not cheap.
