Get a tent if there's any chance of rain.
Find a local caterer and ask for suggestions and menus. What style are you having? Is it formal or informal (how will the wedding party be dressed)? Morning or afternoon ceremony? Any activities at the park or just a beautiful setting?
It's your wedding but if I had mine at a park, it would be semi formal (short gowns for the bridesmaids) and a buffet lunch or brunch. So, I would be thinking of a few simple appetizers paced by catering staff (maybe a seafood like shrimp or scallops in bacon, mini quiches and mini cheese and fruit kababs) champagne, open bar. For entree a buffet: Carved turkey or a chicken dish like marsalla or lemon and capers and carved beef, a potato and vegetable side, a specialty salad (like greek or ceasar) and tossed salad, some declicious breads. Wine at the tables.
Wedding cake, of course.
