I've visited different locations of Lone Star throughout the GTA. They are usually okay. The Newmarket/East Gwillimbury location is fine but sometimes service is enthusiastic to start and then it fades away. I usually have to budget for a couple of hours for dinner as a result. On one hand, you don't like to be rushed but on the other hand, you can wait a long time for food and drinks. The quality of the food is usually fine too, I haven't had any problems. I usually order the chips and salsa (there is now a nominal charge for these), a Golden Cadillac margarita and fajitas. If they could be more consistent with their service, I would improve my overall rating.
