Supermarket shopping in Westchester has always been a frustrating experience -- overpriced produce and meat, crummy selections, few specialty items. The one exception I've found is the C-Town Supermarket on Croton Ave (route 133) in Ossining, an absolutely amazing supermarket catering to an extraordinarily diverse clientele. Ossining has a sizeable South American population, and there are AISLES of specialty goods from Brazil, Mexico, Peru, Ecuador, etc. as well as exotic fruits and vegetables such as cherimoya. What really makes the place so unusual, however, is that there are also sizeable sections catering to North African, Polish, and Irish shoppers. It really demands about two hours the first time you hit this place -- but I've found the best deals here on everything from felafel mix and spiced Moroccan sardines to Portugese pasta, Brazilian gardenia salads, Mexican hot chocolate (your kids will never drink Swiss Miss again!), and Polish jams. The place is like no other supermarket in the county. As an added bonus, there is a woman who sells fantastic homemade tamales out of the back of a station wagon in the parking lot. I don't know her hours, but she's invariably there when I shop on Monday evenings, and a half-dozen to go keeps our microwave humming for the next few days.
