How far outside the Disney bubble? I'm assuming you mean Orlando, but the city sprawls, so how far are you willing to wander?
Orlando has an area known as "Restaurant Row" along Sand Lake Rd in the Dr. Phillips area; there are a whole lot of places up there, but most are high-end chains. It's about 6 miles north of Disney property, close to USIOA.
Closer to Disney property, Columbia in Celebration is excellent for Cuban food. Also, a branch of 4 Rivers BBQ has opened in Kissimmee (it's on Osceola Pkwy, about 10 mi east of I-4).
