Chinatown and Greater Boston in general (with some exceptions) are largely made up of older Chinese milf/gilfs with limited menus. As you get further outside of 95, the menus seem to expand. Examples include Rogers St in Lowell and Worcester/Framingham area amps. Sometimes Nashua or Salem produce some good options. (Southern NH)
If you truly need NY/NJ style amps with Korean providers and a classic amp experience Providence is the closest place.
Over the years, I've found many hidden gems around the greater Boston area but that was my initial stomping ground and I definitely put in the leg work. Quincy/South Shore, CT, Brookline, Waltham/Metro West and all of North Shore on up to NH.
Overall it's not necessarily a bad area for mongering, but it's absolutely more hit and miss than NY/NJ.
I could draw a comparison to NJ as it's just sprawling suburbs full of Amps. (In many ways-and I've traveled all over the country- Eastern Mass and NJ are very comparable in that regard.)
As always with Boston, bring your patience with you. You'll be frustrated if you're used to NJ or NY amps.
Good luck.
