I went to Lone Star for a friend's post-graduation lunch this past weekend. The service was attentive, but my meal was decidedly "meh." When the waitress asked how I wanted my burger, I asked her if they could do medium. She assured me they could, but what I received was way past well-done. I'm used to getting well-done burgers by this point, but this was dang near burned.
I guess this explains why, even with the fairly limited dining options in Monroe, this place is always half-empty.
