My wife & I have been to Lone Star several times, & have yet to be disappointed. The food quality is consistently good, & the service is good as well. The interior is decorated in a western theme, with lots of cowboy boots & other items adorning the walls. The servers all use western nicknames, much like the Melanie Pringle's staff use 50's-inspired names.
Their fajitas are excellent, although the only complaint I could make is that they could put a little more on the skillet for what you're paying. The fajitas aren't cheap, & when I was working in restaurants "back in the day," I know our fajitas looked mountainous compared to Lone Star's. Despite the slightly smallish fajita portions, my wife orders them every time. I've tried various things on their menu & haven't been let down yet. I found their brisket sandwich, peppercorn burger, ribs & fajitas to all be of good quality & their chicken fingers are excellent. When we order a kids' portion for our son, I'm usually hoping that he can't eat them all & that I can help him out.
The prices are about average for a family restaurant & we'll be back there for sure.
