Marina Market St. Thomas Walkthrough. This is the best grocery store in St. Thomas. They have excellent meat and seafood. They also have most all other food items that one would purchase in a grocery store in the United States. It's conveniently located in Redhook a few hundred yards in front of the ferry. It's directly across the street from the Big Bamboo restaurant. We stopped here to buy booze and food for St. John. Please share this video with others.
