I spent one week in Koh Toa and I happen to be bit of a coffee enthusiast. So, when I read about Zest here on Tripadvisor I decided to pay a visit and found out if they lived up to my coffee expectations. Their service is friendly and sandwiches delicious. They locally roast their coffee beans, and being in Thailand I tried the Iced Thai Coffee. Which was delicious. The owner sold me a bag of beans which I tried when I returned home. A very nice locally grown bean with an espresso roast. Delicious! Citrus flavors with a clean finish. My only gripe is about their menus, they can be a little confusing because they group items based on price. So, if you order be perfectly clear about what you're asking for and ask the waiter questions.
