Is this what Alvin Ord's became? There was one in Georgetown back in the late '80s, and it reminded me of Schlotzsky's before they quit caring about the food and sold the franchise to corporate interests.
Didn't care for the one up on Research, but there's one in San Marcos, kinda related still I guess...called Alvin Ord's. The one to get there is the Salvation Sandwich. Basically like Scholtzsky's but the bread's far better and it doesn't suck.
