We will be staying in a cottage in West Bay and will be cooking at home a few of the nights. We would like to grill fresh fish. Where is the best place to buy fresh fish? The grocery store? Are there local fish markets in the West Bay area? Also, we would like to purchase some liquor to consume at the house. Does Grand Cayman produce any liquor? Where is the best place to buy it? Is it duty free at the airport? Thanks!
