I'll be at the Palace next week (June 7th) for the night concert, I'm driving to Vienna after work so I won't have a lot of time to stop and eat on the way there.
Are there food vendors in the park for the concert or is this verboten? If there aren't any vendors I'm assuming it's okay to picnic with a bottle of wine during the concert?
My outdoor music festival experience is mostly North American where we're searched heavily for "contraband" (contraband also includes outside food/alcohol) before being able to enter most outdoor festivals.
Appreciate guidance from anyone who's been in the past few years.
