They definitely card, and a lot of places now won't accept any kind of out-of-state identification. But that's only until the people get to know you.

If you get homesick for the Bronx of bodegas and hole-in-the-wall restaurants, the Hyde Square neighborhood of Jamaica Plain should help treat the symptoms. Although heavily gentrified, the area still is home to many Hispanic-owned and oriented businesses along Centre St headed east from South Huntington Ave toward Jackson Square. Other heavily Spanish-speaking pockets of the city are in the far end of JP along South St, throughout most of East Boston, and in the Uphams Corner section of Dorchester. Neighboring Chelsea is predominantly Hispanic, as are parts of Everett and Lynn and a goodly proportion of the cities of Lawrence and Lowell farther north. In warmer weather the Puerto Rican festival is one of the mega-events of the season.
Boston's North End is the closest thing we have to Arthur Ave.
The adjacent town of Brookline might be reminiscent of Riverdale or Pelham Pkwy since it's a heavily Jewish community with synagogues, delis, lots of Chinese and other Asian restaurants, and - yes - high-rises.
We don't have any streets that replicate Fordham Rd or the Grand Concourse, exactly. Nor is there anything to compare with Co-Op City. No el trains now, either, and our local zoo is hopelessly outclassed by the one in your home borough.
But, welcome - make yourself at home!
