You're right bp78. Any establishment where alcohol is sold and consumed is a no-no for concealed carry in NC.
If alcohol is sold, but NOT consumed then you're OK. That allows you to carry into an establishment, like a convenience store. Just makes sure that the business doesn't have any signage that prohibits guns on the premesis (like the local ABC stores!)
Good question about the wine tasting. I'd have to guess that it's not legal too since both requirements of sale & consumption are being met, even if it's only a weekly event. That would be a question for the attorney general to answer.
Isn't that Totally Wine on Harris Blvd? If so, I live right down the road!
