Non smoking
This restaurant is a cross between fast food and sit down. You order at the counter and pick up food at the counter. The food was good and the service was friendly. Not sure how you coul5s complain about the service since it is self serve.
You can't smoke anywhere in Collin County indoors. Black Walnut is a terrible restaurant. Food is poor and expensive. Service is unresponsive. Don't waste your money.
No
Nope.
No smoking.
No, but maybe you can walk up to the parking and do it
