"Felinfoel" (pr. Vel-in-vole) is still going strong, with its (possibly) most popular beer being "Double Dragon".

And yes, even locals pronounce it 'Feelin' Foul'. It gets a mentions in Max Boyce's "9-3" about Llanelli beating the All Blacks:

Oh aye, the beer flowed at Stradey
Piped down from Felinfoel
And the hands that held the glasses high
Were strong from steel and coal
And the air was filled with singing
And I saw a grown man cry -
Not because we'd won,
But because the pubs ran dry!
