In Winter Park, you have a number of options. Park Avenue has a number of restaurants that are very good, and vary in terms of price/style, etc. The only restaurant on this list that I have not been to is Bosphourous Turkish Cuisine.

In downtown Orlando, Hue is very good. Along with Citrus, and 310 Lakeside (which is the same as 310 Park in Winter Park, just a different location, but not a chain).
I've heard good things about Ember (
http://www.emberorlando.com/) but have never been there.
Thorton Park has good places as well. Dexters is always a good choice (
http://www.dexwine.com).
That should help you get a start. Like I said, they all range in terms of price, etc, to give you options. If you read about a place in particular and want to ask me, please do. I'd be happy to help. Its a bit hard trying to remember all the places off the top of your head so Im sure Ive missed some.
Take care!
