Grenoside..stall selling mussels

I saw this stall briefly as I drove out of Sheffield on the A61 this afternoon.

Never seen it before and I was past it before the name registered.

Does any one know much about it or tried it.

It's part of a weekly event the Norfolk put on, they have various different street food vendors come for one day slots on a Saturday rotation. On a Wednesday they have Nether Edge Pizza Company in doing really nice wood fired pizzas.

Haven't eaten from the Mussel Van, but been in whilst it's been there and the food smells and looks amazing.

Thanks.Ill try to catch it next time around.
