I took a little trip back up to Boston last week. I stayed at my brother's place in Watertown. His neigborhood is kind of a pre-sprawl throwback; little independently owned shops and resturants, local busses, and ethnic enclaves.
Here's a typical block of stores in my brother's neighborhood.
It's a Armenian enclave.
Watertown has lots of spas. These spas are not health spas, but little stores. I think originally they were shops with soda fountains. Spas of this type are an Eastern New England thing.
