Sweet Tomatoes on Kirkman is great if you like buffets. About $5 for all you can eat lunch including soup, salad, pasta, desserts.
We love Fazoli's on 192 in front of Home Depot. Really cheap Italian food, and tastes great. We go there about once a week, and it's only $18 for the four of us.
There is a Steak and Shake in Lake Buena Vista up from the Crossroads, which is pretty good.
