If you find yourself Prague on a cold, rainy day, don't let this destroy your holiday. One of the best experiences you can have while you're traveling in this beautiful old town is to pop into a quaint, old coffee shop and have a pastry and coffee or tea. It's an absolutely lovely way to pass some time while you're waiting out the bad weather. There are countless coffee shops around town and many have fireplaces and very comfortable places to lounge around. There will probably be some students meeting and doing work so it's also a great place to people watch and feel like you're experience a little bit of the local life and culture.
