I like the John Dory

And of course, the counter seats at the Oyster Bar in Grand Central.

I highly recommend The Atlantic Grill. We've been to the one near Lincoln Center.
All are allergic to tree nuts and one is also gluten-intolerant. Hoping for mid-price range and casual clothing OK.
Any suggestions?
