Tiki themes are inspired by the culture and aesthetics of the South Pacific, particularly Polynesia. They often feature vibrant colors, tropical motifs, and elements like tiki carvings, thatched roofs, and exotic plants. Tiki bars and restaurants typically serve fruity cocktails in decorative mugs, creating a festive atmosphere reminiscent of island life. The tiki movement gained popularity in the mid-20th century, especially in the United States, with establishments like Trader Vic's and Don the Beachcomber leading the way. This trend celebrates a playful, escapist vibe, combining elements of fantasy and nostalgia for a tropical paradise, often through music, decor, and themed events.
