So, after Sunday night being a bust, me and the 2 Brits from my hostel last night were up for a big night again. Unfortunately, Monday in Zagreb is just like Sunday in Zagreb and is a quiet night as well. We sat in a few of the open air cafes and grabbed some beers, and also spoke to the locals about places to go out but everyone says that its quiet in Zagreb on Mondays.
One thing that I did notice here in Zagreb is that everyone speaks English - or at least enough to help you out if you are lost or need directions. Everyone is really friendly too....we went up to a group of locals and they invited us to sit with them and were really friendly all night.
