Table service is of the DIY variety (a la Nando's), where you go to a counter, order meat by weight, and then get your sides cafeteria style at another counter. Waiters buzz around the long picnic tables in the main dining room, re-filling your water and bringing your beers.
The barbecued meats appear to only have a dry rub on them, with barbecue and hot sauce available at the table. Generally speaking, I find the Kreuz sausages to be fairly good and flavorful. Where Hill Country shines (albeit dimly) is with their barbecued brisket, which is tender and smoky, but a little dry. The sauce helps here. However, their beef ribs are basically a mass of gristle and fat which requires a herculean effort to chew through.
The sides are decent. Corn bread was good and moist. I also ordered the corn pudding, which is pretty tasty (though a little redundant if you have corn bread). The mac and cheese is a little bland, however.
In sum, I would probably not go out of my way to eat here again, but, if you are really craving for smoked meats, this place is a viable option.
