Crazy that its cheaper in NYC then the three places I've seen it on LI. $19.99. Never had the beer and not sure I can pull the trigger on something like this.
I think it's worth buying a bottle or two, but it's certainly more a fruit juice taste than that of a sour or beer.
I've seen it multiple places as well. Was a bit disappointed, however that's probably due to my heightened expectations. With the quantity available in the city, I'd suggest buying a bottle and trying it first.
