One of the best $1 oyster happy hour deals around (drinks and other foods also in the happy hour menu). 5-7pm Tues-Sat, 5p-close on Sun and Mon. Also consistently great music selection by the bar.

ambience, service, and food rate high in this restaurant. the place is very clean and the staff very efficient. $1 oysters on happy hours! ask for break if you order the mussels, fries, and beer.

Did you say donuts? Offering several different filling flavors, you have the ability to choose what your donuts (4 or 8) will have inside! Very impressed by the selection and they tasted amazing!

Mussels were incredible... Lobster roll was good, but don't waste your time. Any of the mussels will satisfy far more! And of course, get french fries on the side and plenty of bread for the broth.

I have a new favorite: the parma! Crispy shallots and a delicious cream sauce. The best is dipping the bread in it afterwards.

We have been wanting to try Flex Mussels for months and are kicking ourselves that we waiting this long! So many varieties of mussels it was impossible to choose just 1! Order Maine and add fries!

Mussels and Beer, comes with the fries as well, are enjoyable during the happy hour at a good price. Find a spot in the bar section.

I've tried multiple mussel sauces, they are ALL so good, you will need to return several times and try them all. Don't forget to leave room for the donuts, they are a MUST.

Good wine list/cocktails menu. Recommend sharing a few different pots to sample different flavors. The Parma is insane. Skip the apps and instead save room for truffle fries and doughnuts!
Andrew CNovember 21, 2018
Pretty pricey.... but really great flavor and choices of broth for the mussels to soak in!!! Apps and sides are small, but delicious and perfect for share

the South Pacific is a perfect way to get the Thai flavor and still have a white wine base. Lobster roll, truffle fries and donuts are a must. Choco and meyer lemon donuts are tops.
Brittany GoldmanJanuary 10, 2016
Everything starting with the drinks are absolutely amazing! The Thai mussels have so much flavor and are absolutely incredible
Russell HirschornMarch 14, 2016
Nice dining room, clamstrips were 99% breading, thai and dijon mussels were great, overall pretty expensive. B. Cafe laksa mussels are better, less expensive and come with fries.

Bombay is one of the best mussel dishes I've had at a seafood restaurant. If you're looking to try something new, I highly recommend. Salted caramel donuts are also a must.

If you love mussels, this is your place, especially when it’s $20 for all you can eat mussels during happy hour. We like the Fra Diavolo or The Mexican.

The Parma mussels are so incredibly good. Who ever said cheese and seafood don't mix? Heavy. Will not be able to have desert. The Italiano are great as well. Service is spot on.

Was apprehensive because mussels are a lot of work & not always big portions. Absolutely not the case. Great, numerous flavor selections. Very filling. Truffle fries, donuts, kale salad, and mussels.
Joo RoMay 25, 2013
Go mussels. And don't forget to get flex donuts for dessert. Salted caramel donut is to die for. You're welcome.
Matthew SpectorFebruary 15, 2015
Nothing more nourishing than a giant pot of mussels. Avoid the complex offerings and spring for the classic white wine mussel meal. Great doughnut dessert course too.

A seafood lovers heaven, Flex makes the N-Siders list for the most amazing mussels in NYC! We suggest trying Thai, Bombay, Provencal & South Pacific pot! Save room for the salted caramel doughnut!
TingJanuary 2, 2016
The Mexican mussels has just the perfect level of spiciness to leave your mouth with a tingle. Don't miss the beignets also.
J.T. TrollmanMarch 25, 2013
Not only are the mussels amazing, but the desserts are to die for.
Kiwi WangOctober 4, 2016
Such a good neighborhood staple. Consistent and delicious. Surprisingly awesome brunch!! Get the stuffer bagel donuts- crazy crazy good
Sophie ParksApril 4, 2015
Mussels & truffle fries. Experiment with the pots that have a cream based sauce... Might sound weird, but they're amazing to the last bite!
Arnab MukherjeeJanuary 13, 2013
The Bombay mussels are fantastic!!!! The doughnuts are a popular dessert. OpenTable messes up reservations so make sure you call and confirm a day in advance.
Rachel Wang PangNovember 10, 2015
What can I say, big bucket of mussels, they got different options of how u would like it cooked, overall a nice place in NYC
Joe WrightFebruary 2, 2011
The Thai mussels are fantastic as is their often changing beer list. The calamari appetizer is huge for two and to top it all off they apparently have a secret menu item of booze filled doughnuts.
НатальяJuly 11, 2018
Very Good oysters! Mussels are 3 out of 5 and a little bit overcharged.
Paolo BaroneFebruary 12, 2019
Great place, excellent food and awesome service. Definitely a place to try on the upper west side

Lobster bisque mussels were out of this world. Drank the broth like a soup at the end!!!
Sasha JonesAugust 4, 2017
My favorite restaurant of all time! Such a fun atmosphere with delicious food and friendly people!
Kevin GrantApril 10, 2017
The doughnuts were an amazing surprise. Imagine cream cheese filled doughnuts with bagel toppings. YUM

Probably top 5 fave restaurants for me! Mussels 25 different ways. Definitely need to be a seafood lover, which I am! Great wine too:)

Happy hour special sounds awesome (!) but it ends so early (6:30pm). Really enjoyed the Parm mussels- highly recommend them!
KristiFebruary 23, 2013
Amazing restaurant! The Bisque, Maine, and Fra Diavolo are all very very good! Salted caramel doughnuts for dessert are a must!
Arun NandiOctober 15, 2017
The salted caramel doughnut was special (2 for $5). If you're not a fan of mussels, this place isn't going to change your mind.

Flex Mussels is one of the best restaurants in New York, much less on the UES. From the Éphémère beer to the many varieties of mussels to the incredible lobster roll, Flex Mussels never disappoints ( Read more
Mary CrippenJune 20, 2013
The truffle fries are amazing! As is pretty much anything you could order on the menu. Also, delirium tremens on tap.
Janice KarbachinskiyMay 3, 2016
don't forget about their brunch!! the messiest sandwich ever was exactly how it sounds and delicious
Justin GuminaAugust 19, 2013
Amazing service! The "fungi" mussels have bacon and mushrooms! Don't forget a salted caramel donut for desert!

Reserve a table. Arrive early, grab the tasty Canadian brew on tap or the fruity sauv blanc. Chat up friendly staff. Order Old Bay fries with any of the 23 mussel recipes. Down the broth wholesale.
Brian EricksonJanuary 3, 2015
Really enjoyed the curry broth it was so good. Satisfies my craving for Indian food while my wife can have italian.
YaniqueAugust 28, 2014
The seafood is orgasmic,enough said! Make your reservations early though to ensure you get a decent seat.
Ashley HardeeFebruary 15, 2014
Thai mussels are amazing if you like curry coconut flavors. Best mussels I've ever had!
EmmaJanuary 11, 2016
Mussels were too cooked but the sauce was excellent (I had the classic one), fries are crunchy and tasty.

When you can't finish a pot of mussels, order the lobster roll. It's good.
Jennie D.November 13, 2013
I used to not like mussels until I came here - Flex has made me a convert! The Parma and Thai mussels are unreal.
ZenFoodsterAugust 15, 2017
HH food + drink specials ALL-day Sun's & Mons + Tue-Sat 5-7pm. See attached HH menu!
New York HabitatDecember 9, 2011
When at a restaurant with mussels in the name, it should be obvious what to order. The real prize however are the truffle fries.

Get the Parma mussels!! And don't forget to have the salted caramel donuts for dessert!!
