The main Agora is from I.Dragoumi str to Diagonios area and from the bay to Egnatia str. There are many small boutiques with excellent items and in various prices. I think the best is Tsimiski str.

If you want something old or antiques, in cheap prices there is the Bit Bazaar next to Venizelou and Olympou str.

There are many new restaurants and bars with great food, dont forget Thessaloniki is a gourmet destination.

Regards from a sunny Thessaloniki. Kostas
