In a section of town that Queens Central Steve would call East AQUA, but I would call AQUA proper (now there's a debate that could go on for hours), the Brothers Coffee Shop is for sale. Buy it, put in a little work, and reopen as a higher-scale diner. The kind with cool music and great breakfasts - colored chalk on the specials board, you know what I'm talking about. You'll make a fortune on me and Steve alone.
However, being a few doors down from the new Starbucks, it's possible that another chain will take over the space. With a CVS and Kinko's, and the aforementioned Starbucks, what little (1120 sq ft) chain eatery might be next? My guess - Subway (sorry Steve, I know it's not what you were looking for).
