There are dozens, if not a few hundred, restaurants of all types within 7 or 8 miles of Bonnet Creek. So I think it depends on what your cost/quality expectations are.
Our family likes places like...
Bahama Breeze - either the closest one on Vineland Road or the newest one on SR 192 near Orange Lake Resort;
Celebration Town Tavern - in Celebration;
Raglan Road - at Pleasure Island in Downtown Disney;
Big River Grille and Brewing - at the Disney BoardWalk complex;
ESPN Club - also at BoardWalk;
Miller's Ale Houses (also known as Orlando Ale House and other place-name Ale House) - the new one on SR 192 near Orange Lake Resort seemed nice but the quality seems to vary from restaurant to restaurant in this chain;
and there are many, many more in the general area. There are several recent thread on this board that speak to a variety of restaurants. I'd suggest reading through

).
