Cherrys is very hit and miss. You never quite know what you are going to get in the way of extra's.
But it's a large underground parlour and it's an interesting place to visit. Rooms are ok and fairly spacious.
Cosmo is a stones' throw away, so I usually visit one and then move on if there is no one I want to see.
Prices both the same £40 for 30 mins and then £10 for owo if on offer.
