We drove past this place once and missed it, the building and signage don't stand out too well. The restaurant was very dark inside, and because we were eating a late lunch, there were only a few other people eating when we were seated. Our waitress was very friendly, and the burgers we ordered were hot and tasty (we ordered a Cajun burger and a buffalo chicken burger and split them). The waitress even offered to cut them in half for us when I told her we'd be sharing. The fries were pretty darn good too. I'd love to go back and try the steak next time we're in Alpine for dinner.
As a side note, I didn't use the restroom, but my husband did, and he said it was awful unfortunately. Pretty run down, and the commode handle was broken and you had to flush by putting your hand in the tank. Hopefully they've fixed that. Other than that the food was great, the restaurant was clean and the service was quick. We would definitely visit again.
