This is the Chisholm Trail Restaurant in Skidmore. It doesn't look like much, but the noon buffets are great. I don't normally go though Skidmore, but there has been work on 239 just before Kenedy and now with the newer highway that bypasses Sinton, this has become the preferred route to San Antonio.
They are closed on Mondays and no buffet on Saturday. It is worth the stop.
