From my sole visit, I would have to say that this is a pub of contrasts.
First though, the consistent aspects. The beer is uninspiring -- all cooking lager, with the exception of Guinness. Drinks prices are steep - £3.70 for a 330ml bottle of lager. Service is glacially slow. Food is, apparently, not too bad (although I didn't try it myself).
As for the contrasting aspects of The Regent, these seem to be based around the venue's two large rooms. On my visit, the front room was pleasantly lit and furnished, and full of beautiful people. The back room, however, was a diabolical hovel -- dark, sweaty, deafeningly loud, crowded to the point of complete immobility, full of rude, braying, elbowing tossers, broken glass on the floor, and so on.
I won't be going back.
