Ladies! Would anyone be able to suggest a reasonably priced food van, based in Wales? We want possibly something unique, but if not, a pizza or a burger van will do. It would need to be a savoury van, who'd be able to cater for around 70 people. We've had a look at a few online, but we'd love to hear some first hand experiences, rather than blindly guess! Thank you all XXX
