My girlfriend and I went to Ian last night. The food was absoloutely perfect in every respect. Ahi poke was better than anything we have ever had in Hawaii. Her ribeye was perfectly cooked and exactly as requested (medium rare), accompanied by the Chef's "dirty" sauce which we loved. He is very good with flavors. My chilean sea bass was sublimely flavored and textured with just the right combination of tastes...complex yet not overwrought. Even the small touches like the bread were amazing. The server chopped fresh oregano in an olive oil confection that also included red pepper and garlic in which to douse the crispy bread. Lovely! My desert, a trio of Hawaiian Chocolate was original, distinctive, and not cloying.
Now for the bizaare part. The decor is cheap...hard banquette, industrial ceiling, etc. and incongruous...kind of middle eastern and doesnt suit the cuisine at all. The service, while attentive, is not professional enough for the quality of the food.
Overall, I would highly recommend Ian, and we plan to go back again soon. In a sea of overrated and overhyped restaurants in NYC, Ian really stands out.
