You need to remember that Boston/Cambridge is a college town.

You are a block away from Newbury so you are in walking distance of plenty of places. I enjoy Sonsie, but thats me.
You are also near Mass Ave which has a ton of ethnic bars and places to eat.
North End
South End
Theatre District
Harvard Square
