Great Homestyle Food!. AJ's deli is a great place to go and get some of the best homemade food around Bethel Park. Their hoagies are absolutely delicious as well as their awesome monstrous burgers! The soups are all homemade and are some of the best I've had! Definitely worth giving a shot of you're looking for great food. I've had their breakfast as well and it's better than going to any other local place for breakfast. They also have a huge selection of deli meats and cheeses that are available for purchase by the pound!
