Parking does exist (at the back of the car park), but it's not obvious. The vast majority of people just leave their bikes propped against the wall near the door.
The bike parking which exists is rather bizarre heavy plant pots with a bike symbol and loops to lock your bike to. The positioning of the loops is awkward and having a plant in the way doesn't help.
As this shop is on NCN 8, it would be really good to see them welcoming cyclists with a prominent sheltered bike parking area with proper stands near the door of the shop.
