Footreads, you or your son been to Campania in Bay Ridge, 99th & 4th? I'm still working way through menu but both pizza and entrees are excellent. I like Colandrea New Corner also & shit, I can't remember name but there was excellent trad red sauce joint with low key "mob bar" (allegedly) on 13th Avenue & 72nd or so, in Dyker for years, right by still extant Krispy Pizza...

re: Ozone Park, + Bangladeshi on City Line (Brooklyn) side of Liberty Ave + Guyanese all over Richmond Hill... Fulton St in Woodhaven majority "Spanish" (both islands & Central America).

Back to Williamsburg, real estate $$$ were still relatively low and space avail that as recently as 10 years ago there were still textile shops right on Metropolitan between Graham & Bushwick Aves, with many more stretching up into Bushwick proper and Ridgewood.

I know some people have had mixed experiences there but I did well at Frost Seafood many times.
