I tattoo at a beautiful studio called Un1ty Tattoo in Shrewsbury.
The address is:
6A Greyfriars Bridge, Shrewsbury, SY3 7DS
Google maps link here.
If you are driving there are three nearby car parks. In order of closeness they are St Julians, Wyle Cop, and Abbey Foregate. How busy they get is the inverse order. If you are coming on a Saturday I would probably just park at Abbey Foregate. It is cheap and still only 5 minutes walk. St Julians (the closest) is likely to be full (unless you are very early) and then there is a long route of one way systems to get back to where you need to be.
There are limited spaces for an hour of parking on the street Longden Coleham right by the studio.
If you don’t drive the studio is 10-15 minutes walk from the train station.
