One of our favorites is Sweet Tomatoes. They have 2 locations in the area. The newest and closest is at Crossroads, the shopping center located on 535 at the end of the road coming from Downtown Disney past all the hotels.
It is an all you can eat but without all the deep fried everything found at most. You enter to a huge salad bar with every salad ingredient and topping you can think of as well as a variety of prepared salads.
Then there is a station with baked white and sweet potatoes with various toppings, a couple of pasta dishes and several breads including a 4 cheese foccacia and a garlic bread (yum).
There is a soup station with 6 or so delicious freshly made soups and toppings for those.
Finally, there is a dessert bar with soft serve ice cream, some type of warm cobbler, pudding, fresh fruit and some other goodies and toppings.
All of this is just $9.59 per person. I think it is one of the greatest deals around. The food is delicious and fresh, the service is always good and the place is clean as a whistle.
