Looking for Boston leads...

I'm looking for some leads on the following for Boston:

Hotels:
I already know about the Boston Omni Parker House (it's on the Freedom Trail), Lenox (Back Bay) and Onyx (downtown).

Coffee Houses:
Boston Tea is a local chain. I got no other leads.

Restaurants:
I know to go to Parker House for clam chowder and Boston Cream Pie.
Clam shacks, lobster houses...a good place to get a plate of steamers and a lobster roll. I know about Legal Seafoods and Kingfish Hall.

Bars/Taverns:
No leads yet.

Cannolis:
I've decided to eat my first cannoli in Boston. I just need to know the best place to get one.
