Awesome food - breads, breakfast options (eggs, salmon sandwich with Philadelphia cheese), The Banitsa - Queen of all - try all the varieties, you won't regret it and it's made with cheese, eggs, olive oil, extremely delicious.
The sweet options and thousands of varieties of cakes are absolutely worth it. A bonus - they're so tasty, the calories don't count :D.
Don't forget that Ayriyan is Banitsa's best friend and HleBar offer an extremely delicious one which is not dilluted with water.
If you feel adventurous, check out the bio Boza, which is worth the price.
I read people here complaining about the prices, but the prices are actually normal for the quality of the products this bakery uses to bring the best on the counter.
You also have the option to grab a cup of warm coffee or buy some of the bio products they offer - flour, milk, youghourt, chocolate etc.
Absolutely recommended!
