I'm not sure that's the same as going for brunch and getting as much wine as you like though. Unless you have to queue up at a Prosecco station and serve yourself of course. Which could get very messy.
If this offer had been available at any local establishments around 15 years ago then I can guarantee that my friends and I would have bankrupted them all within a six month period.
As it is, I'm far too old for that shit.
