Best Shellfish Tower
If you love oysters, then I'd do an oyster tasting at Aquagrill. Otherwise, I'd head to Balthazar or Blue Ribbon Brasserie (I really like their New Orleans shrimp & I think they have a slighter larger selection). Lure's is overpriced by a little bit and I didn't think the quality was as good. I also love Pearl Oyster bar but usually end up getting the lobster roll & the fried oysters, less so the raw bar stuff.
