Finding a Venue for event (Ho Chi Minh City)

Hi everybody,
My name's Hằng, our team intend to organize an event about travel. 2 guest speakers. A founder of Singapore Travel & Culture Meetup, also acting as a TEDx speaker gathers with a young Vietnamese travel blogger who at the same time is author of the book "Ta ba lô trên đất Á"
The estimated number of participants is: 50~60
We want to find a warm, cozy place, but Bright spacious.
Does anyone know where we could organize such an event like this in HOchiminh City on 29th, Aug, at 6:00pm ?
Pls let me know if you have some idea about it. Many thanks
