Banana Mama Rooftop Bar & Kitchen Saigon is a rooftop bar on the 10th floor of Mayfair Suites near Bui Vien in Ho Chi Minh City. It serves burgers, cocktails, and french fries, and the cocktails and french fries are good. Most of the customers are foreign visitors, and at night the Ho Chi Minh City skyline is visible from the bar. It is outdoors, so it can still be hot at night.
