Balaoritou-Sugrou area (Βαλαωρίτου Συγγρού)
Note that this area is totally different during morning, you will see only small shops, but at night is a party place full with young people!
You can find small clubs-beer pubs and restaurants
One of my favorite places to go for ouzo/tsipouro and have some tapas is called
Kafeneio Tesseris Epoxes (4 εποχές)
There is a terrase coctail bar next to it called Urania but I don’t know if it open yet
Pizza Poselli is also realy good place to eat and is at the end of the next block
In general this area has many places to go! feel free to explore
