I used to eat at Lone Star a good bit and went over there for the first time in a few months the other day. We may have hit it on a bad day, like I said it's been a while, but I was not impressed. We stood there for a good 10 minutes waiting for the cashier to acknowledge us as she ran around making some BBQ sandwiches. I didn't mind the wait but she could have at least spoke up. The food was also not as good as I remembered it being. Give it a shot but if you get bad service or food let us know.
From a South Carolinian's blog, Mustang Rolling, I quote:
"Well, here at G & G Barbecue, 6622 Savannah Hwy., Neeses, SC 29107, they are open Friday, Saturday AND Sunday."
I cannot vouch for the quality, having never been there, and am not sure it's on your route. But hey. It's barbeque on Sunday.
