Romantic Boston neighborhoods?

Travel Info
What neighborhoods in Boston would you recommend for walking around on a nice summer evening after a romantic dinner?

Travel Tips

Back Bay, North End, or Beacon Hill. Especially the waterfront around the North End. Plus there are fantastic restaurants there, and Mike's Pastry for dessert, which is not to be missed - and then you can go to Christopher Columbus Park.

I'd start in the North End, of course. ;-) You can stop in a cafe for dessert/coffee, then take a walk along the Harbor Walk. http://www.bostonharborwalk.com/index.ph...

Have a fun, romantic night, wherever you go!
North End
North End - Very italian like.
North End, no question, I agree with everyone else. Newbury Street can be nice to, but the North End is definately the best choice!
