Oasis convention centre is a beautiful venue.
They host wedding, parties, graduations, pretty much anything.
I've personally had two graduation parties here, and come to two NYE parties that Oasis typically hosts every year.
The hall is beautifully decorated, there are 3 main rooms you can rent with lot's of space for large parties (or weddings.)
The food is pretty good.. it didn't overly impress me both times at NYE but was your standard Portuguese/Italian fare.
I can't really say anything bad about this hall as it's a pretty nice venue.
The only tiny thing I would recommend is, when planning the NYE parties, there should be an option to pay with debit/credit.. not everyone walks around with hundreds of dollars in cash.
