GUARANTEED: if you open a California-style make-your-own burrito type place, it's a no-brainer. Everyone likes it, and there's no competition here for this. Chains such as Chipotle, Moe's Southwest Grill, etc. are the example, and they do incredible business wherever they open. You get to choose your meat (beef, chicken, etc), add any veggies you want (grilled onions, peppers, tomatoes, broccoli, olives, whatever) and cheese, then have it wrapped up in tortillas and grilled. Low overhead for you, and easy to take out for us---which would be excellent, being right next to the Publix.
Thai would be great too, but the burrito idea requires less money to get underway, because the decor can be basic and you don't need gourmet chefs to make it. Of course, if you can find a *good* Thai cook, go for that too!
Hope this sparks an idea for you....
