Don't really know about the bars on campus for beer, (although i think it's all around the £1.70 - £1.90 mark) but the Sugarhouse (our student union night club) is quite reasonable for a night out:
The bars on campus have fairly stable prices. They're all the same, as far as I'maware. But campus prices range depending on what you're buying. Carling is £1.75, Guinness is £2.20, and ale prices vary.
As for bars in town, they range, but the two wetherspoons and the two scream pubs (keystones & the friary) are cheap.
Hey, I worked in Grizedale bar but they're all the same on campus... Carling - £1.75 Strongbow, Worthingtons - £1.70 Coors, Grolsch - £2.15 Guinness - £2.20 Vodka shot - £1.30 (with mixer £1.45) Most other shorts (JD, Southern Comfort, Malibu, Archers etc etc) are £1.60/£1.65 + 15p mixer! And for the non alcoholics - cans of soft drinks are 55p ranging up to £1.20 for a J2O.
I'm missing being there farrrrrrrrrrrrrrrrrrrrrrr too much!! x
