not sure what type of food you're looking for but Jersey Shore BBQ in Belmar has amazing catering at VERY reasonable pricing. Just did a graduation party with them and we had zero leftovers - people were licking their plates. We did the St Louis Ribs, Pulled Pork w/ slider buns, coleslaw, baked beans and mac n cheese for about 25 people and I believe it came to around $200. They even threw in some cornbread for free!
