nice meal for wedding night ???

After we get married in Central Park next March 27th , at the night, we'd like a nice meal with my 2 children (20 & 18 ).
I want it to be a funky, buzzing type place with lots of atmosphere, BUT still 'nice' .

Any suggestions? Somewhere in Manhatten, easy to find and not too pricey !!
thanks for your help.
