One of the worst.
Went to Lone Star on Friday night with two friends. It was extremely uncrowded, yet the service was quite slow. My sirloin was fatty, overcooked, tough, and bland. The salads were decent, but the baked potato that came with my entree tasted like cardboard. The bread comes with a very strange butter as well. The bathrooms were not very clean, and the atmosphere was seriously lacking (blaring country music, bad lighting. waaaay too cold). Choose another place for affordable steaks, this one's not worth it.
