Krakow is a great place to visit but can be a bit overwhelming and easy to get lost in the backstreets. With a little forward planning it's suprising how many places there are to get tasty Vegan food!
Happy Cow is a great resource to research before you travel.

Here are my top 2 places to eat great food at very resonable prices.
Cafe Młynek, plac Wolnica 7, 31-000 Kraków, Poland
Lots of Vegan options, Good location in the Jewish district.
Krowarzywa Vegan Burger, Sławkowska, Kraków, Poland
Excellent place to eat, lots of choice on the menu and close to the main square.
Krakow is a great place to visit for the history and the Vegan food :)
Not forgetting drinks and the vast selection at the House of Beer!
Świętego Tomasza 35, 31-027 Kraków, Poland
Can't wait to go again!
Cheers
