I have to rate Lone Star a 5! They have the absolute best chicken fajitas anywhere. And it's not so much the chicken part as much as its the tortillas part. OMG their tortillas are to die for - cooked one at a time in a special oven right there in the restaurant.
I've always been seated quickly. The restaurant is pretty big, so there's lots of space. The free chips and salsa are awesome and served right away. The wait staff is friendly and quick. And the food never takes more than 15 minutes when I'm with 2 people. (Went with a group of 8 once and it took a wee bit longer.)
I would definitely recommend Lone Star to anyone looking for a neat place to eat!
