Legends @ Legends
Grey Street, Newcastle
Admission: £1 Friday, Saturday and Monday 21:00 - 02:00
Venue: Nightclub
Music: AOR / Retro / Rock / Metal / Industrial / Goth / Punk / Alternative
Facilities: Three big bar areas and a big dance floor and stage. Toilets are easy to get to and not much of a queue. There is also a big cloakroom and a hotdog stand at the back of the dance floor.
Review: Everyone in there is your friend, everyone just goes to have a good time and there is no trouble what so ever, and if for some reason there is like some smelly charvas get in, then the bouncers kick the **** out of them before they say "WELL AYE"
Other: Little Jeff has moved there and the music selection is great. He plays best part of the many requests that he gets and the female bar staff are definatly worth a look at.

Trillians
Princess Square (behind Northumberland St), Newcastle
Admission: Varies if bands are on Daily 11:30am - 11pm Sun-Wed, 2am Thu-Sat
Venue: Pub / Late Bar
Music: Rock / Metal / Industrial / Goth / Punk
Drinks: Average
Facilities: Reasonable priced bar with daft vodka cocktails and good food
Review: The atmosphere in Trillians is electric and being one of the few Rock/Metal Bars in Newcastle everyone wants to be there. It's Like a big Happy Family. Everyone is friendly and they are all there for one purpose! Rock!
Other: Where as Trillians isn't the biggest bar in the world, it more than makes up for it in other department's.
Trillians plays host to many good bands and has an amazing sound system. And the booze isn't too expensive either.
Hope this is of some help to you.
