    The bar was a bit disappointing - avg drinks and $13 for a mocktail was too much! Saving grace are the mussels and frites. Huge mussels and oh so tasty. Should have skipped the lobster roll. Excellent staff.

    We had an amazing experience at flex mussels! We ordered the scampi, lobster roll, truffle fries and had brownie as a dessert. Our server Janelle was really sweet, nice and helpful. The restaurant is pretty crowded though and it’s very noisy inside, so we decided to sit outside. They do have heaters, but it wasn’t as warm as inside - so it’s up to you! I felt a little bit cold in the end. Overall, it was a nice experience and will be back to try the Diavolo mussels!

    I've been to Flex many times, but this was my first visit to 3rd Ave. Wonderful as ever. Prettier space and the mussels are as delicious (and generous) as ever. Our server gave very specific, helpful suggestions and managed to satisfy my very precise dining companion. I have to return for happy hour.

    New neighborhood restaurant. Crowded on a Sunday evening. Tables close together and hard to hear conversation. Food was interesting and flavorful.
