Has anyone been to Opia on E. 57th St? I'm wondering if the food is any good, and (because it's in a hotel), what the crowd is like? I'd be going on a date and we're young 20s. Went to Triomphe in the Iroquois Hotel a few weeks ago, and the place was empty. Am looking for a restaurant with good food, and good vibe. Please feel free to make a different recommendation.
