Grilled piglet van

I saw this van whilst walking in Brno and took a picture, sure that its text could only enhance the illustrations: a chef at a barbecue, a pig, and a stein of beer.
I was right. According to Google, the van advertises "piglets grilled to order," a "year-round garden," and that the Grilled Piglet Van does "celebrations and banquets." How excellent! I wonder if grilled piglets taste different than grilled pigs...
