I went into the Owain Glyndwr for a quick pint whilst I was staying in Cardiff. The pub has TV's all around for when the sport is on the box. I went in there when the Rugger was on and promptly walked out as it was so full. I went in there again yesterday when it was quieter. The pub is nice and spacious and I believe there is seating upstairs. I found that the staff that I met were friendly and helpful. I will definitely be going back there again when I am back in Cardiff.
