Uhhh... Unfortunately (or fortunately, depending on how you look at it) there are no real "interesting" streets. Jamaica Ave. from 85th st. to 102nd st. is a main road with lots of retail businesses. Largest names are Duane Reade, McDonalds, Popeyes. The smaller shops are salons, pizzarias, liquor stores, grocery stores. The coffee shops are mainly owned by immigrated South Americans. Some are still Italian owned as this was a predominately Italian neighborhood several years ago.
All of these areas are still pre-yuppie/hipster. It might be too rural-ish for the single life. Lots of houses with some small walk-ups and pre-war buildings mixed in here and there.
Transit is on the elevated J train. Also public buses criss-cross everywhere. And there are express bus lines that shuttle commuters into midtown on nice comfy charter buses for $6/ride.
Crime is petty. No art or music scene. Lots of evangelical churches though.
