Well, I will not write about my special days, it's Rome we are talking about now. Living in UK or US, or Russia, you probably will expect restaurants and shops open 7 days a week and without a lunch-break. Not in Italy! Let's see:
Sunday - Domenica - is a great holiday every week, all local shops and most of the non-touristic part of the center will be closed.
Monday will shut down local restaurants and bars, as well as small shops.
Tuesday is very special as well - fresh fish arrives to the shops and supermarkets.
Thursday - after 1 pm most of the local shops will be closed (don't ask me why)
Friday - fresh fish arrives again (so, you can buy it Tue-Wed and Fri-Sat only)
Is it already special enough? Next time I'll tell you about working hours :)Not so simple there either!
