Generally use this car park when I am shopping in Sainsbury's below as it brings you out opposite and next to Marks & Spencers. There are 4 levels you can park on (the first is staff only) including the roof and it has an elevator as well as stairs. I am fairly certain it charges for 0-2 hours so you may be better off going to an alternative car park if you are planning to be under an hour.
It is well lit and payment is on foot when you have finished your shopping - payment machines next to lifts/stairs read more
