Last time i went, they were totally disorganised. Made an appointment, they confirmed. I rock up to the appointment, they say i had to wait 5 minutes. No problem. 10 minutes later i ask and they tell me Sorry, wait half an hour, we had walk in 15 minutes ago. I said, i had a booking, and the walk in gets priority? Rude response from the guy, you wait or go.
Never gone back.
