Ernest Klein & Company food supermarket is a refreshingly well-stocked place to buy food among a number of shoddy convenience stores and mini-markets. They have a full selection of both fresh and packed food, including a sizable section for frozen foods.
For hotel dwellers, they have a good deli and prepared food counter that has soups, salads, and sandwiches. The list of available drinks, but alcoholic and non-alcoholic, is excellent. Also freshly packed fruits are a good option, especially as a healthy snack. The store is also a good starting point for a picnic in the Central Park.
