Our dinner at Ostra was sensational. It was slightly difficult to locate their entrance, but once inside we were warmly greeted by the host and a elegant aesthetic.

Solid seafood in a clean, modern setting. I had a great time here. The oysters are incredibly fresh and clean, which is a big plus. Their paella is also a standout — rich, flavorful, and highly recommended. The monkfish, however, is just okay; pretty average and nothing particularly memorable. I’m not sure if they still offer the seabass tartare, but …

The food at OSTRA was truly delicious. The Boston lobster for $135 was absolutely worth it — so much sweet, generous meat. But the real surprise star was the gnocchi with truffle — rich, aromatic, and perfectly executed.
