Oyishi Sushi on 80th is the best hole in the wall you’ll find on the Upper East Side. It’s well known for takeout omakase, but the real magic is eating there fresh. The space is tiny, maybe six or seven seats inside, plus a couple of outdoor tables, which makes it feel even more special. The staff is incredibly warm, but the star is the fish. The otoro is mind blowing, the seabass is perfection, and everything tastes unbelievably fresh. It’s simple, no frills, and just so good. If you know, yo
SUSHI WAS THICC AND EXTREMELY FRESH Love this place down, the service was amazing, waiter extremely friendly and offered my friend and I free sake but we turned him down. Ambiance was nice, I loved their playlist, every song was a hit in my books. My friend and I got the nigiri chefs choice and maki box, both of which was scrumptious! They did not have a tip suggestion or anything that implied tip was required, but service and food was so good, my friend and I tipped NYC standard anyway.
This is probably the best sushi I have had ever! The freshness of the tuna was like no other and I have had many tuna rolls before. I really enjoyed the atmosphere of the place, it felt really comfy and the service was really nice. Definitely will come back to this place when I am in NYC again!
