You haven't said where you're staying.
On Disney Pleasure Island would be a good choice with a number of clubs and restaurants to choose from ( you can eat at DTD if you prefer then walk to PI) , another choice on Disney would be Boardwalk. There are a number of restaurants and clubs there ( again you can eat at any of the restaurants in the Swan,Dolphin,Yacht or Beach club hotels before walking to the clubs on BW)
If you're near I-Drive Universal Escape has some good restaurants ( I like Jimmy Buffet's margaritaville, but Emeril's is the "quality" restaurant there is you fancy upmarket) and clubs. For a more relaxed ( non dancing) evening, Bahama Breeze on I-drive is nice food and usually has live reggae music played at the outside bar. Cafe tutu Tango gets good reviews as well.
