This one is a typical one. A Bakery for everyday, where you can meet Locals eating and having a rest there. If you want to experience the Local lifestyle in Thessaloniki, I recommend to go there for a coffee filter with a Greek sweets
It is located on the west district of the city center, six minutes walk to the Modiano Market.
Here, they sell traditional salted or sweet pastries and meals for lunch.
The good thing : they have a tea room upstairs, so you can stay longer to have a rest, with heater on winter and air conditioner in Summer.
