Full disclosure: I come from a very cold Northern US state, so to go to an Ice Bar in the middle of a rainforest was a trifle absurd... but also so much fun! I went with my siblings, and we got such a kick out of being surrounded by Argentines and Brazilians geeking out of the ice snowman and being in parkas.
You pay 300 pesos/person, and you get a half hour experience, including unlimited (pre-mixed) drinks. The drinks come in ice tumblers, which admittedly is very fun. The drinks were pretty sugary, but they worked. All instructions were in Spanish, so know that before you go. Also no credit card payment accepted.More
