Uhm, I never spend 100.-, let alone more, for a night out at a club
20-35 entry, 3-5 beers = total cost 70-80 tops
Or
20-35 entry, 2-3 cocktails, 1-2 non-alcoholic beverages = total cost 100 tops.
Sans club and just at a bar, 4-5 beers or whatever = 35-50 depending on where you go
Granted, if you want to get pissed drunk, then going out to an actual club vs a bar will indeed set you back quite a bit.
