I think virsa is sikh heritage, de is of and punjab is place in Indian subcontinent. Together it would mean sikh heritage of punjab.
It is an Punjabi Indian restaurant. A literal translation would be the heritage of Punjab. The culinary transaltion would be when you eat the 'Dhaba Chicken' here. The menu in general is good and rich. You can taste the Ghee and Butter in several dishes :).
As information, Punjab is a state in northern part of India.
