Rainbow Bay A-Frame Pavilion is an outdoor, open-air venue in Honolulu offering a large, tented space with multiple tables, parking, and clean bathrooms. Reviewers note it's affordable and spacious enough for big gatherings, though there's no air conditioning, so heat and outdoor pests like flies and mosquitoes can be a factor—renting during cooler months may help. Used for weddings, birthdays, and other celebrations.
