It's unclear to me if the JPY44,000 price is per person or includes a larger party (I checked the link and you are given an option of 2-4 people in your party). If this is the price for up to a party of 4 for 2-hours of free-flowing champagne, then it's an incredible bargain since Krug costs at least JPY25,000/bottle retail. OTOH, if it's a per person charge, it's still somewhat of a bargain, but how many of us can drink 2 or more bottles of Krug in 2 hours by ourselves to make it a bargain? Of course, it also includes caviar, but with that as the only food item, the alcohol will all go right to your head in no time and you could wind up passed out on the street. It seems like a devil's bargain.
