My first guess would have been Eddie V's, upscale seafood restaurant, but they seem dedicated to Ponte Vedra. Next guess is McCormick and Schmick's. A Portland original now owned by Landry's. Their fresh fish and oyster daily menu and upscale style both fit Jax and the Federal Reserve building. Thier price point is an ATL, Charlotte, Jax target. Also, the website promotes event space.
