For good old-fashioned tradition and real ales, the historic Goat Major pub is one of the city centre's finest drinking establishments, just down the road from Cardiff Castle.
Despite its very central St Mary Street location, this Brains pub attracts a well-mannered clientele rather than the rowdy, drunk crowds filling up most of the other bars in that area, so it's not the place to go for a big party night - but great for conversation over a quiet pint (or spirits from the Penderyn distillery). It doesn't lack atmosphere, however, and it can get really busy on some nights. When the rugby's on, things in there are a bit different, but I generally avoid the city centre altogether on rugby days (because I could not be less interested in watching sport, and every single pub seems to be filled with people staring at screens).
It's also clean, well staffed, and serves decent if unadventurous and limited pub food - but still offering good value for money.
Although for a brief period the pub was renamed The Bluebell, it's now reverted to its former name - which apparently comes from the establishment's close association with the 41st Regiment of Wales, with a goat as their mascot.
