City Centre, Belfast
The bar was fire-bombed in 1991, since then the interior has been restored to its 1846 design.
I spent my time in the saloon bar, but there are other options. Fibber Magee's hosts traditional Irish music, BT1 bar in the basement & a nightclub in the loft.
Benedicts is a bar/hotel not far from the city centre. There is always a mixed crowd there - different ages, different styles, the only common thread is that everyone is happy and there for a nice evening out. It is a great place to people watch, too.
It is a sort of neo-gothic place with a restaurant upstairs (food is quite nice, too) and very loud music.
Dress Code: Usual rules - no trainers (running shoes), no track suits.
A list of a few nightclubs in Belfast:
The Bot (upstairs) - Can be packed and quite young though, but fairly casual.
The M-Club - more of a dance music club
The Welly Park - Bit of an older crowd, so a few quieter areas for talking as well as dancefloor area
M.I.L.K. - If you're a bit of a poser go here.
Culpa - bog standard nightclub
Dress Code: most are no trainers places, some are no denim. nothing too drastic.
Here's a few decent bars (not nightclubs) worth a visit maybe:
Botanic Inn - bit studenty, but ok.
To be honest bars in Belfast are much of a muchness and all serve beer so it's all good.
Dress Code: nah
