    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.

    It was moderately crowded in the late afternoon on Sunday. We were seated at the two people table which was quite small for the amount of food we ordered. Also we did not have any space to put away our bags and winter coats so ended up sitting directly on our own coat and having to keep our bag on our lap. The mussels and burger were good but lobster roll was very disappointing. It tasted bland. The customer service was not bad. More space should be given to travelers for stuff.

    Great for brunch! Beware of many families with their babies! Service is ok…nothing to rave about! Food could come warmer! Especially the Shelly eggs Benedict!

    Great service - every single person! Very appreciated & food was almost as good! The tuna tartare was recommended to us and it my favorite of what we ordered! It's a seafood based menu, a great spot for pescatarians. Only compliant was my cocktail. Highly recommend this place & glad I found it.
