We had a super good Espresso! We talked for a few minutes with the owner and she is lovely and kindly! The also have a lot of cakes and fresh food like croissant and pan au chocolate European Style. Superb view on the back of you want to relax for a while. This is the place to stop in between Medan and Lake Toba!

Visited this cafe for the gelato, but quite disappointed to find that their selections of gelato were almost finished by the time we arrived at the cafe, but we proceeded for lunch anyway. We ordered Kwetiau Kangkung Belacan, Chicken Casablanca, Ice Longan Tea, Kedondong Juice, and desserts. The food was good, with just the right portion. The drinks were too sweet for our liking. We enjoyed the Italian and beach vibes of the place, and enjoyed our time there.

This place offers more pastry and they are one of the best this town has to offer. The drinks are excellent too. The prices are certainly affordable. The downside is this place is too tiny.
