The Malt Loaf in Conwy, N. Wales has a consistant mix of performance/sessions every night, except Sundays, I believe. Monday is an open stage/session w/all attending taking turns onstage. Great pub w/warm people and a good mix of abilities. The Cambrian Hotel in Aberystwyth has Tuesday night performance/open stage sponsored by the Cambrian Folk Club. Usually there's a featured guest along with the open stage, but not always. On Wednesdays there's a 'session teaching' gathering led by a gentleman by the name of Peter. He's a gifted teacher/player and loves traditional music. He conducts the session like a class and if you're an experienced player you may be a little bored as he gears things to the person of least ability. There's another session at the 'Tap and Spile' in Bangor, but I'm not too sure when it's held. These were my personal favorites for a variety of reasons.
