The Weatherspoons are generally decent run pubs - it all depends on the clientele. There are 4 in Manchester City Centre. 3 of them are decent but the one in Piccadilly Gardens (by the bus station and tram) is a nightmare. Generally the scrotes will walk to the cheapest and closest pub. If you want to drink with decent company then don't go to the cheapest pub in an area. They will have a lot of decent people in them but they will attract the scrotes.
