D J's Market & Deli is a long-standing business in Cosby, known for its food and as a local stop. It is called the greatest place in Cosby to get food, with really excellent pizza. After a period of decline in food quality, it is now getting good food again according to a long-time customer. The market serves as a convenient spot for cheap gas, drinks, snacks, and lottery tickets, though you must pay inside as credit cards are not accepted at the pump. The location is noted for staying open later than other area businesses. The kitchen in the back makes sandwiches and fried foods. The Philly steak cheese is very filling with a ton of meat, considered the best in the area by some, though not a true Philly steak. Other items like fried mushrooms are great, served with a good orange sauce. The employees are described as friendly and nice, and the cook has been known to accommodate customers even while cleaning up to close. The place itself has only two pumps and is not the cleanest, with no restrooms, but is valued for its cheap gas and food offerings.
