Although there isn't anything special about it's architectural composition, the fact that it's city's main square and the fact that it's situated near the seaside, it is a must-see when in Thessalonik

Lovely square/ area with PLENTY options for food and drink. Awesome night vibe. Some places are open until 4am which is great. Good prices too.

it's a vibrant part of the city; we spent hours there meandering around eating drinking watching getting entertained we felt very very safe but because the younger kids don't have money or are not al.
