Just asked someone where we are staying. Last time it was a chain cheapo in town - it's a footy tour after all. Think we have a game on the Saturday day so no idea where that it.
We went down by a waterfront last time too - what's down there?
general townie type bars, unless you go to Stereo which is a really good bar more music driven than townie clientelle driven if you get my gist.

Apart from MarkB's bar

other bars I would suggest personally are
Stereo
Tokyo
Head of Steam
Florita's
Other Rooms (part of Digital in the gay triangle)
Living Room
The Apartment
Baby Lynch
These bars are nr Central Station.
Most of the bars on the Quayside (Waterfront are typical generic bars with special offers on drinks etc etc tend to attract the "on the pull crowd" on a Friday

)
You then have The Gate - which to me is basically a shopping centre but with bars instead of shops - not my cup of tea but it incorporates Tiger Tiger and some of the bars have house DJ's playing - personally its ok if its raining or cold outside then you dont get wet going from bar to bar - avoid if weather is nice - its not that special.
Jesmond - has a good selection of bars with outside areas - a bit nicer than town in my opinion but you might find it a trek if you are staying on the Quayside - still its 5 mins away in a taxi or you can walk to it in 20 mins...
You wont get in any bars in the size group you are in - split into smaller groups no more than 4/5 or get chatting to girls and go in with them - a mixed larger group isnt so frowned upon.
Pity you werent staying over on the Sunday night - Stereo have a funktasic night til called Bloc Party and the music was amazing last Easter Sunday some crackin resident DJ's on from the various club nights in town..... I would have said that was a better option than the club option to be honest
