The food was fantastic - we ordered the mixed platter and received Ital Stew, rice and peas, veggie chunks, salad, and more. We also tried one of the many available elixirs, Baba Roots. The server (also an owner?) was an incredibly positive, friendly Rastaman who clearly cooked and served the food with love. This was hands-down one of the best meals we had on the island. We were utterly satiated and pleased at the end, and honestly quite surprised that at 6PM on a Friday there was only one other diner there: if this place were here in California it would be packed constantly!
If you go to Treasure Beach, do not leave without trying Gee Wiz. You'll get the chance to try real Ital food, speak with genuinely kind servers/owners who are happy to chat and answer questions, and enjoy a bright, cheerful restaurant setting.
