About pasta-the majority of restaurants that advertise serve mainly pasta dishes.
Main grocery stores:
Kirks- on the outskirts of Georgetown and the airport. Has pretty much everything you need including a salad and prepared food bar.
Fosters- the shopping center behind the Outback on West Bay. Has the biggest selection and the best prices for grocery items, especially rum cake (CI$11.95).
Hurleys- on the east side of Georgetown; smaller and more expensive than Kirks and Fosters.
Side note: if you decide to purchase rum, the duty-free shop at the airport has the best prices for rum.
