Unfortunately, this steak house has gone the way of so many before it.... Boring! They took away, from the menu, my favorite treat; prime rib. They used to have this amazing rub that made the meat delicious. Now, not so much. The sides are tasteless and the prices remain high. Not worth it, especially when its location happens to be...

The menu offers a variety and the food is very good. I did have a bad experience with luncheon steak that was very tough, but the manager made up for this by giving me a free steak. This is an exception though and I wouldn't hesitate to recommend this restaurant.

my wife and I shared 2 steaks: sirloin and rib eye. Both very good. Waitress was very pleasant and did a good job.

Our party of 12 opted to have dinner here since we were all staying at The Hampton Inn located a short stroll behind the restaurant. The service was excellent. Our server, Angelina, is the living definition of efficiency! We are not a demanding group. Humor tends to abound and Angelina fit right in. The food is exactly what you'd expect... More

Food and drink was good. Service was excellent as we also had 6 kids to deal with...Had the burger and the "ultimate" margarita" which were both good.

A group of 9 of us went in on a Tuesday night. We had two servers assigned to our table. Our food was fast. Steaks were cooked the way we ordered. All 9 orders we spot on. Fun place to eat and walking distance from our hotel.

My husband and I visited this restaurant shortly after moving to the area. We went based off of online reviews. The service was excellent. The food was really good. I registered online with the restaurant website and was able to print out a coupon for a free appetizer. The manager sent us over an additional full appetizer plate with 4... More

Swung in for dinner and had prime rib. Service was great, food was only average. Not much else to say.

Had a hankering for steak and thought we would give Lone Star a try. We were greeted at the door and seated right away. Our server (Ryan) stopped by within minutes and went over the menu with us. His service was great overall. I did have to chase him down for steak sauce but otherwise he did very well. The... More

The food is good but the staff is not the most friendly around. A little customer service skills could improve your visit here. Reasonable pricing and most of the time the food is prepared accoriding to your liking.
