Well this is a tough one for me because I love offsite restaurants even more than those onsite! I'll try to keep the list sensible.
Tommy Bahama's Tropical Cafe at Pointe Orlando;
Capital Grille at Pointe Orlando;
Seasons 52 at Sand Lake Road (this had never appealed to me much - seemed a bit too "chainy" from what I'd read - but we decided to give it a go in January and now I understand why it gets rave reviews. Delicious food and an even scrummier setting. Oh, and they also have ZD chardonnay on their wine list);
Old Hickory Steakhouse at Gaylord Palms;
Cheesecake Factory at Mall at Millenia (we like to sit at the bar for lunch and share a selection of appetisers);
Brio Tuscan Grill at Mall at Millenia (ditto. I like the lunch portion risotto);
McCormick & Schmick's at the Mall at Millenia (it's
so difficult to choose where to eat when we go there. PF Chang's is probably our least favourite, but that's good too. And now there's the Village Tavern which I keep reading about and feel compelled to try!

);
Forte at Reunion;
Eleven at Reunion;
Orlando Ale House;
David's Club at the Omni Championsgate;
Ruth's Chris at Sand Lake Road;
Norman's at the Ritz-Carlton;
Cala Bella at Rosen Shingle Creek;
Margaritaville.
The following is a list of some of those on my "to do" list. I'd be pleased to hear any reviews.
Roy's at Sand Lake Road;
Press 101 at Dr Phillips;
Oceanaire at Pointe Orlando;
Maggiano's at Pointe Orlando;
Dan Marino's Tavern on the Lake (although I understand Dan Marino no longer has anything to do with it. Not sure what happened there - it hasn't been open long

).
