I really doubt you'll have problems locating a place to watch as most premises will be looking to maximise profits during that time. Having said that a few places that come to mind are Souled Out, Hartamas Square, Laundry and Library. Almost every small pub will bring in a projector as well. If you are looking for outdoor parties, I'm betting there will be heaps seeing as every brand across every industry will want a piece of the action. Usual suspect locations are Sunway Lagoon, 1 Utama highstreet/park, Curve, Jln Bukit Bintang and Mont Kiara. Sorry but I can't help with mamaks.
