Historical version 2 of Kazbar
This is a friendly place housed on the corner of a side street and Cowley Road, meaning it has a large conservatory in the front, as well as plenty of hidey-holes in the main space in which to chill out. I haven't been here for a while so I can't remember exactly what the prices are like, but they do a reasonably-priced lunch menu with beer.
The traditional way of experiencing Kazbar is an extended sunny weekend afternoon drinking copious amounts of Sangria and periodically ordering tasty tapas. This, however, gets expensive.
