Can't think of any that matched that description! The 'Coffee Shop' in London Road was a hangout for quite a few that were into 'controlled substances' for a while, but that went about 30 years ago. The only other 'tea room' that I can think of was 'Nightingales' in the Bishopric, but that was more a pensioners meeting place - very genteel clientel. A girl friend of mine worked there as a saturday job.
