Golden Krust Bakery is a chain of Caribbean take out shops in NY (primarily the boros but they are branching out). This is the closest one to me and I go there often.
We're fans of the meat patties (chicken or beef) which are freshly made and delicious.They also freeze well which is a blessing when I can't travel to the shop.
Golden Krust also prepares hot dishes like curry goat, stew beef, soups--and it is a popular spot in White Plains for take-out. Sometimes the line is long, but be patient, it's worth the wait.
You can get products from the Caribbean like Horlicks, and ginger beer at these stores.
