It’s LOOONG been that way in Allegheny County (Pittsburgh), PA.
Restaurants have to pay through the nose for a beer/liquor license, so many don’t have one. Customers are free to bring their own hootch, though (which in turn can only be purchased at special “State Stores”).
Also, in PA, due to taxes upon taxes upon taxes, restaurant wine is way more expensive than state store prices might hint.
Adding the recent 10% Allegheny county tax on top doesn’t help either.
