Description: In the main station there are now 3 sets of toilets. They have removed the 30p charge but they are all located on the paid concourse, so you will need a ticket to get to them.
There are toilets upstairs (Grand Central) which do not require a ticket. The cubicles are not great, half don't lock, they are filthy and not much room for understall. These are up the escalator after entering the station from the corner (under the digital eye) by the tram stop. Toilets are opposite the Cat Cafe.
