Mangosteen | Our Story
Rooted in passion, made for St. Pete
Mangosteen is a tropical Asian-inspired restaurant in downtown St. Petersburg, where Southeast Asian flavors meet Japanese culinary craft. Built on a genuine love for bold food and an open table for everyone.
From dishwasher to founder
Sean Thongsiri began his culinary journey as a dishwasher at 9 Bangkok Thai on Central Avenue — the same street where Mangosteen opened its doors in November 2021. That personal history with St. Pete shaped everything about how the restaurant was built.
Southeast Asian soul, Japanese craft
The menu spans yakitori skewers, creative sushi rolls, dumplings, noodles, and a dedicated spread of vegetarian and vegan dishes — all rooted in Southeast Asian and Japanese culinary traditions.
The room that welcomes you
White-brick walls, turquoise accents, backlit mirrors, tropical plants, and palm wallpaper create a warm escape designed for guests who come back often.
Always a seat for you
Mangosteen now has two downtown homes — St. Petersburg and Dunedin — each with a full-service bar pouring seasonal cocktails, sake, and more.
