I plan on visting Austin and the surrounding environs (Lockhart, Luling, Elgin, etc.) and plan on visting as many BBQ joints as possible. Since time constraints will force me to eat at a couple of places a day, I don't want to fill up at just one place. Do places typically have smaller sampler portions or is everything served Texas-size? What would be an appropriate order for two moderately hungry guys who wish to try two or more places in a matter of hours? Also, what are the essential sides to try at a typical BBQ joint in these parts? Any and all ordering tips and standard procedures would be greatly appreciated.
