The Athenian market. Every day except Sunday there are markets in various districts of Athens and Piraeus. The largest market is the market Varvakios (ΒαρβÎ¬κειος αγορÎ¬) on the Athinas street (between Omonia and Monastiraki). This is an indoor market which is also open daily except on Sundays. This visit is worth it, because almost all Greek products are for sale here and at very favourable prices. In the Varvakios buildings you can find also a number of restaurants where you can sit and eat low-priced. Varvakios plays an important role in the Greek economy, they say, especially during national holidays prices are formed on the basis of the prices charged here.
