The Burrrt has gone I'm afraid. No more revolving dance floor. No more puking off the deck into the tyne. 🙁
The area around Central Station is pretty lively these days, although one or two places aren't too keen on having stag parties in these days, (Revolution in particular). Centurion (in the station) is a good place to start, (especially as you can fall off the train, straight into the bar).
If you want really good food, without ridiculous prices, try Blackfriars. Some of the best contemporary british cooking you'll find in the area. The Living Room is also worth a try, as is Red Mezze near St James'. Stowell Street is the place to go if you like good chinese food in large quantities.
