"My top pick and the perfect place to start your walk in Koukaki with a full brunch on the go. Fresh ingredients, wide variety of breads and lots of passion! Ask them for their suggestions and be sure that they will take the time to satisfy you. I still can't get over the salmon or the beef choices and definitely the red pepper pesto. Next to it try the beetroot juice with mint and ginger. PS: You can't go wrong with Guarantee!" - Natassa Pappa

Best sandwich we’ve ever had! The best in Athens, if not in Greece. All the ingredients were fresh, and you could choose from different ingredients to build your own sandwich. Super tasty and the staff was really friendly. We were sad we found this place on our last day in Athens — otherwise, we would have eaten here every day!

For me, its save to say its the best sandwiches i’ve ever eaten. You might think, how good can a sandwich be? I can promise you, if you bite into one of their sandwiches, it feels like you went to heaven. Not only are the people working there super nice, the place feels authentic, the meat and sausages they offer are delicious, the caramelised onions and grilled veggies are amazing! I tried a suggestion from the menu and chose one myself from the many fresh ingredients they offer. We were in Athens for 4 days and came back everyday! I hope this place will always exist in athens, it will be my first stop whenever i come back to the city! Maybe they can expand and open a shop in my home Rhodos too, i guarantee, i’d go there everyday and be your best customer 🩷

I love this sandwich place!!! It’s phenomenally great. The sandwiches are DELICIOUS, Freshly made whilst you wait with fresh delicious ingredients and the bread is so good, warm - I wish I could give this place 10 stars. It’s that great. The owners are so incredibly friendly too - there’s a fresh juice section and the juices again freshly squeezed. Sandwich selection is so great, there’s such a great variety to pick from. I had the aubergine, courgette, cheese, apple chutney, rocket - had this twice and wow, DELICIOUS - everyone needs to try this place. Prices are so reasonable too. And your sandwich is packaged thoughtfully too. I will revisit & revisit this place. And recommend to everyone. Best sandwich place by far!

I discovered this place totally by accident, but it is a true gem. The sandwitches there are something else - fresh produce, high quality ingredients, amazing flexibility to build your own - great quality! The staff is also very friendly and ready to give you any suggestions on pairing options :) Value for money is also great - for around 10 EUR you can get a big sandwich that covers Lunch with no issue and also a big freshly squeezed juice. 5/5

Choose from 36 pre-composed variations of sandwiches or create your own. You won‘t be disappointed. Very friendly staff. Fair prizing. Take-out only.

Very high quality and great service with employees who are eager to help you make the most of your trip with recommendations and proposals. One of the best sandwich shops in Athens if not the best. The juices are also really good -- especially the one they recommend as their best seller.
