Best British Boxing Venues

Where does the British contingent on this board consider to be the best atmosphere for a night of boxing in or around the UK?

Manchester (Arena), Liverpool (Echo Arena), London (O2 Arena, York Hall) Nottingham (Capital FM Arena), Cardiff (Millennium Stadium)? I'm certain I'm missing a bunch of great venues. What say you?

Newcastle Glasgow, and most prem grounds if our crappy weather sorts its self out
