I felt it was important to post this so that people would know (maybe not as important as some other posts I've made, but still good to know if you are planning a trip to Paris). At the top of the Eiffel Tower, they sell champagne! But be forewarned: it is 12€ a glass for the cheapest glass. Totally worth it, but if you are traveling on the cheap, BYOC comprenez-vous?
