Boston is totally a foodie place but pizza is not their strength (no good BBQ either), their seafood & shellfish is their strength and so are mixologist type cocktails.
Definitely NY pizza, in Massachusetts finding decent pizza has been a quest there are so many ehhh places, and they have no idea what a pie is so don't call it that, nor do they seem to know how to make a calzone, I had have the ricotta added custom.
In our years here we discovered Ernesto's in the North End is outstanding, plus you can grab a slice and walk which is oddly unique here for some reason.
No idea what is happening on the North Shore but we have two places we like South Shore, one is NY traditional and the other is more flavorful but sort of floppy like a home made pizza.
The 2 unique things here are deli sandwiches with "hots" which is a hot pepper relish kind of condiment and also a Roast Beef 3 way, which is a delicious mess.
