Texian is a combination of Southern patois, with touches of Spanish, Irish, and German, and a lot of mutation of its own. If so, the treatment worked. Food is another consideration, seeing as how the Riverwalk area next to the Convention Center in San Antonio is full of the stuff. Texas barbecue isn't quite as good as Memphis barbecue, if only because Texans use beef instead of pork, but it has its moments. Kidney beans instead of pinto beans are barely tolerable, but no reputable cook in Texas would ever serve chili with elbow macaroni unless they were trying to cover the distinctive flavor of dog or water moccasin.
Beer is another sore subject.
Most turistas make the assumption that to attain the Texas experience, they must drink at least one bottle of Lone Star. Folks, Lone Star is a foulness used in this state to rip off tourists and strip paint, so shun it at all costs. Now, longtime conventioneers will laugh at me for saying this, but San Antonio offers a lot to do besides wander around the Worldcon. Catty-corner from the convention center is the Ripley's Believe It Or Not Wax Museum, and then we have the whole Riverwalk to play with. The Snake Farm still has the pit full of rattlers, but the Austin branch of the Animal Liberation Front whined about it, so now they have to feed the rattlers in the off-hours when the patrons can't watch.
