1. The party starts early.
Mexican pre-party is know as precopeo, literally “pre-cupping.” We gather at a friend’s place or small bar to get a little bit woozy and ready for the night. Precopeo has several benefits: avoiding the traffic inferno that is Mexico City every Friday afternoon, saving some money (since drinking in a club can be quite expensive), and getting to know your party mates better in a more relaxed and conversation-friendly environment than a thumping bar or nightclub.
But beware: overindulging in this practice could end up in you missing the big party altogether. Too much precopeo is the main reason people don’t make it to the party.
