Anybody recommend a good Beauty Salon/Spa in York?

Me and a couple of friends are going to York for the day one Saturday for my birthday and fancied booking ourselves in for some kind of treatment, maybe a facial or manicure, or both! Anyone got any recommendations? We'll be shopping most of the day so it will need to be in York city centre where all the shops are. Don't want to spend more than about £30 each.

beauty brands??
