The Shoppes at Palmila
8:00 a.m.-9:00 p.m Monday-Saturday, Sunday 8:00-4:00
If you must buy something imported from the U.S. and are willing to pay top dollar for it, then go here. They cater to the high-end crowd, and have a decent selection of healthy grocery items, and gluten free choices, as well as health supplements you would find in the states.
The deli in the back of the store has some good options and I do like their fresh squeezed juices and smoothies, but be ready to pay US prices. Do not waste your money on a gluten free muffin. They look yummy, but looks are deceiving.
