Brunch, bakery, and Beatles in Chalok.
Fresh-baked sourdough, smoothie bowls, specialty coffee, and a resident cat named Ringo Starr. Open every day 07:00 to 17:00.
You came for coffee. You stayed for the cinnamon rolls.
Bright, airy, and unhurried. Garden seating, a board game in reach, Beatles on the speakers, and Ringo Starr probably asleep on the best chair. This is the kind of place that turns a quick breakfast into a long morning.
"This was the best brunch we had in Thailand. Their cinnamon rolls were huge and so good."
"Probably the best coffee I had on Ko Tao. Bread tastes like straight out of Germany."
"The owner is a photographer and sells really unique postcards of the area."

Art and Koh Tao prints.

Made from scratch, every morning.
Mellow Submarine is a Beatles-themed brunch cafe and in-house bakery on the main road in Chalok, run by a couple who have called Koh Tao home for over six years. The cinnamon rolls come out of the oven before 7 am. The sourdough is baked fresh each day. So are the croissants, bagels, focaccia, and brioche buns.
The owner is a photographer who sells postcards and prints of Koh Tao in the cafe, and hosts occasional art workshops. The gallery wall changes. The cat does not. Ringo Starr has been holding down his spot since the beginning.
Everything on the menu is made in house, from the house mango-chili sauce to the homemade ice cream and cheesecake. Beatles music plays throughout the day, and the dish names do the rest: Day Tripper smoothie bowl, Love Me Do, and more. Vegan, vegetarian, and family friendly. Board games available. Free WiFi. Metal straws and free drinking water always.
"Best breakfast on Koh Tao, hands down."

"The best brunch in Koh Tao! The food and drinks are delicious, good portion, reasonable price for the quality, and especially very good service."
"This was the best brunch we had in Thailand. Their cinnamon rolls were huge and so good. Very fast and kind service too!"
"We came here for both our two breakfasts in Koh Tao! Friendly staff, lovely food, nice atmosphere, really recommend the smoothie bowls. I like that they use metal reusable straws and provide free drinking water."
"My experience at Mellow Submarine was notably pleasant from start to finish. The fruit bowl was impressively fresh. The eggs Benedict were simply exquisite, beautifully prepared, with perfectly balanced flavors."
"Probably the best coffee I had on Ko Tao / Ko Phangan / Ko Samui! Sandwiches are insanely good, bread tastes like straight out of Germany."
"I had the Day Tripper smoothie bowl, one of the best I've had ever! The menu items were Beatles songs, which is quite fun. I also appreciate their sustainability practices, no plastic straws as in most places on the island."
"Lovely and charming place with great staff. Everything here is yummy and there's an added bonus of an adorable Ringo Starr kitty cat. Can't recommend enough!"
"Seriously the best coffee on the island (I get the americano). And the food is spectacular. The atmosphere is relaxing, open, airy. The owner is a photographer and sells really unique postcards of the area."
