Shopping: for the best selection of wine, Big Daddy’s at the intersection of West Cross Road and South Side Road (called Foster’s Corner). Wines from Chile and Argentina are reasonably priced and considerably better value than wines from Europe or North America.
Each of the three grocery stores has a few slightly different products. Most of the foods are American products that come in by weekly barge (ocean conditions permitting).The selection dwindles steeply every day in the interval between barges, so buy it when you see it. Some prices are double what you’d pay in the U.S., others anywhere from nearly equal to 50 percent higher.
Most stores and businesses are closed Sundays, except for the dive shops and eateries. For Saturday arrival, plan on shopping right away (stores are open until 8 or 9), but you could also eat out or bring some food from home to get you through until Monday.
For fresh fish, check the fish cleaning sheds at the various docks until you encounter someone cleaning their day’s catch. On more than one occasion, usually around noon, we surfaced from a dive to find fish for sale. They don’t advertise, you just have to ask ($4 Cayman dollars a pound is reasonable.)
Water: The island has a reverse osmosis plant to desalinate seawater. It is delivered to house cisterns by truck. If you’re not used to it, you may be better off drinking bottled water (though it’s perfectly safe if boiled for cooking, or for tea or coffee). On the West Cross Road (on the west end, it connects the north and south side roads) is a small hut that dispenses purified water for $1 a gallon (use 4 Cayman Island quarters). Once you buy a gallon at the grocery store and use it up, you can then reuse the jug at this hut and save some money. When you leave you can drop your empties at the hut for others to use.
