I never counted how many restaurants there are in Chania but I guess that if you included all eating places, from souvlaki joints via tavernas, ouzeria, fancier restaurants and workers cafés in the covered market you might well get into three figures….
That's a lot of restaurants for a town of just over 60.000 inhabitants. It's also a lot of good restaurants: consider that many of those stay open all year around and don't just target the tourist market. If they are going to survive with such an intense competition they will have to be good.
But still, the quality of eating places can change fast
