These are the last of the local Toltecas, at least in name. The local chain is still owned by the Cedillo family, but the other Delaware locations have been renamed La Tonalteca. Casual. Lunch and dinner.
From the February 2010 "96 Favorites" story:
The last of Las Toltecas stand sentry on Wilmington’s bustling Concord Pike, still doing wild business by giving customers exactly what they want—flavorful versions of their favorite Tex-Mex dishes and tasty Margaritas. What’s made Tolteca stand the test of time? How about the marinated skirt steak that finds its way into parrilladas, or the fresh-tasting house made pico de gallo.
