are you looking for stuffed baked steamed accompanied by steamers pasta chowder great wine selection, micro brews, ...its endless.
If you are looking for steamed lobster steamers and so on, Boston is not where I go for that although I have had many dinners in the city where the lobster was amazing.
I live on the S Shore so right here at home is where I have had some of te best. Some of te small lil clam shacks have te best fried clams nothin fancy but tasty for sure. Sorry I cant help you more than than.

Now this is the down and dirty place to go, right next to the Intercontinental Hotel, you buy your lobster and go outside and sit at a picnic table and eat it.

For night clubs,

Good clubs for dancing:

This the so called place to be seen in Boston.

One side note, if you are out all night and get the munchies, go back to Splash, and right on the corner is the South Street Diner, a true diner, with hot goth girls and all the club people go there.  Might find out were there this a good after hours dance club


Hope this helps

Venu is also decent.  Boston does not have a big club scene.

If you come to the Cape Spankys right on the water in Hyannis.  The lobster Salad you will never finish alone.  The lobster roll is the same way.......Enjoy!
