A friend of mine and I got into a debate about this last night. I had one on my last trip, and loved it (I'm also a sucker for optics), but she told me I was nuts. Has anyone had it? What did you think?
Worth it is very subjective - you were willing to pay that price and you loved the drink, so in your case, yes . Someone who ends up not liking the drink might say no. In Europe mixed drinks are expensive (though usually not $33 expensive), and if higher quality/price alcohol is used the drink is priced accordingly.
In the end, all that matters is that you are ok with it
