My girlfriend was visiting from Ireland and we both love seafood so had to try Grand Army. Had a reservation for 8pm but found ourselves there early. Still got a table, and the manager reassured us that early is good! Our server was polite, knew everything on the menu backwards, and gave us the perfect amount of attention. To start we had a dozen oysters, served with home made tinctures (the pastrami!!!!) and a portion of devilled eggs which were deliciously seasoned. The oysters were some of the freshest I've had in Brooklyn, well sized and reasonably priced. For our mains we shared the mussels and the grilled octopus. Both were perfect! The octopus was tender, and the mussels were huge and full of flavour! Our drinks were a perfect accompaniment to our dishes, refreshing and light. It was a perfect evening, and I can't wait to return in the future!
