i've only be to the original one in manhattan, on the upper east side - but i believe the menu is the same, and much of the staff on 13th st started at the uptown branch.
the mussels are excellent - they prepare them 23 different ways, they have good oyster selections, and a killer pastry chef.
don't set yourself up for disappointment - it becomes a self fulfilling prophecy

Agree -- was there for the first time (UES) on Saturday night. Lively crowd, mussels were solid -- I had the lobster broth and chunks of lobster. Girlfriend had the Dijon. Frites were good as well (have to order these a la carte which is a bit annoying). Many of the broth flavors looked appetizing. Needed a reservation on a Saturday night but they hold all the seats up front (bar and counter) for walk-ins with a list which is managed by the hostess (which I appreciated, saving the hover-and-mad-dash for bar seats).
Name may not be great but definitely not a gimmick -- they do mussels well.
