Actually there are two big venues. The smaller had a great selection of rock groups, then dancing and hip hop prevailed.
With our free tickets compliments of our accommodation, Berkeley Globetrotters (part of the Glasgow backpackers group of hostels), we even got our first drink free. In any case, the drinks were not expensive and the people were serious party animals. We met a lot of nice people and for two girls it was a friendly party atmosphere rather than meat marketville.
The street was alive at four in the morning and we happily walked back. In fact, it was such fun we returned the following night. Next visit to Glasgow was to see a group playing here and as a venue it is superb.
