When I lived in Wales I liked the Cwm and Llantwit Workment's Hall. Cheap booze, snooker and pool table, food was OK. The wife wasn't keen, mainly because of the line on the floor 6 feet from the bar that women weren't allowed to cross, or the room with the arcade machines that women weren't allowed in. This was 2004.
There was a pub in Tonypandy that was rotten though. Wish I could remember the name of it. The food - chicken curry, with naan brad and a big dollop of (unasked for) mushy peas. The pints were warm, the floor sticky. The wife refused to drink anything not in a bottle, it looked so manky. I only had a couple of pints and was sick for most of the night.
