Or, leaving at exactly the same exit, if you drive 2km along the SS49-E66 you come to Area Di Servizio Lanz:
Raststätte Lanz Südtirol - Herzlich Willkommen!
This was surprisingly pleasant when I stopped there just 4 days ago. It's not cheap cheap, but the quality is way up there. Easy to turn around and return to the autostrada.
