My hubby and I stumbled on this place on our way back from Fira/Oia hike. It was such a delightful spot to eat with yummy food, great service, breezes, and a Caldera view. We returned several times during our week in Santorini. The potatoes were one of my favorite dishes.

Whatever you do, DONT order the breakfast deal for just under 10 € unless you want weak coffee, artificial orange juice, 2 thin slices of bread, a tiny shop bought croissant with tiny cheap jam/honey containers and a bowl of yoghurt.
I refused to eat what was on offer and they still made me pay €8 Euro for 2 terrible coffees.
The view is however amazing from this spot so just order other things from the menu as the other food on offer looked good.
My advice would be to remove the breakfast deal from the menu as although it sounded ok it’s not what you would expect from a place that has relatively good reviews.

I ordered the yoghurt, honey and nuts & here and went back the next day it was so amazing. Had coffee from here a couple of times- it was nice nothing great. The front part with the view wasn't open at any of the times we went but we passed it a lot- it looked lovely however the back part was nothing special.

The new terrace at Mes Amis has a million dollar view of the caldera and Oia. It is a great place to watch the action on the water and the sunset. The staff were wonderful, chatty, friendly and helpful. The food was great. It is the perfect spot for breakfast and brunch, and we returned for a lovely dinner to watch the fireworks from the volcano. Highly recommended.

On average this was one of the cheaper places we stopped for lunch. It has a lovely balcony overlooking the water. The pizza had such great mozzarella on it - note you could probably share a pizza between two.
