help!!!!

so I'm being baptized (I'm 29) what foods would you normally serve afterwords (it's being held at my church during a service) i was thinking of having everyone come back to our house and do a cook out (we'd provide the meat and have people bring a dish to pass) but then i was like why not have everyone join us at a nice restaurant and just have everyone pay for there own meal or go the traditional route and do finger foods and platters at church but then what would you serve HELP!!!! also what should i wear someone plz help me i want everything to go smoothly
