Wonderful bartenders and wait staff. Great beet salad and delicious grilled octopus. Mussels to die for. Excellent lobster mac n cheese and grilled salmon. Ate far too much!

My hotel recommended this place, and they were SO right to do so. As a Canadian, I was thrilled to see that Flex get their mollusks from Prince Edward Island-- fantastic quality. The dinner menu is cheekily divided into "Mussels" and "Not Mussels". Delicious oysters to start, then the Mussels 'Bisque' were superb (with lobster, brandy, tomatoes, garlic, and cream).... More

My wife is a mixed media artist and we were visiting The Ink Pad just around the corner which happens to be one of the few remaining artist supply stores in New York. We were hungry and decided to have lunch at this wonderful little restaurant which also happens to have the greatest t-shirts that the staff wear. This place... More

My husband and I ate here while attending a business meeting on the upper east side. With reservations, you are seated quickly in this bustling casual restaurant. They have mussels (and other seafood) in a dizzying variety of preparations. My choice was a tad spicy, and I like spice. The donuts for the dessert are full size donuts - so... More

Went here 11/13 the restaurant is average size very well decorated and clean. The only thing I didn't like was that the tables are to close together. The service is exceptionally great and food is likewise. Well recommended for a great meal.

This place has been like a magnet for me for several months. Its facade is very attractive and the idea of a restaurant devoted to mussels very compelling. In the event, I had a dinner time to myself and decided to see what was really there. For starters, the restaurant is much larger than it appears with three rooms each... More

Had just finished up a few hours at the Cooper Hewitt museum and wanted something nearby. We were able to get a last minute reservation at 6:45 on a Saturday, too. The smoked Salmon appetizer was very good and the Mexican mussels were flavorful and perfect for dipping the fresh bread into. We also got the truffle French fries which... More

A bit off the main road from Lexington and 82nd street on the east side. Nice atmosphere. I still prefer the mussels experience at Lowe's, Paris. Mussels are smaller here and not as tasty. $30 per order. Octopus and fried oysters were good. Open only for dinner 530-11pm

As a family, we absolutely loved this place! We're big mussel fans, so having a restaurant where there are over 20 different choices of ways to have them was ingenious! We don't have anything like this in London! We all had a different style of sauce with our mussels and each one was so tasty in it's own way. My... More

This restaurant is a few blocks from the place of a good friend. I've been here many times, and loved the experience each time. Management remembers repeat customers (an essential in NYC), and is very gracious to each. I love the truffled fries, and each type of mussels, to be sure, are just superb. Wine selections (Muscadet, of course, for... More

Staying in Upper East Side
