Banh Mi craving

Hi folks

I’ve been travelling for eight weeks now and will be in Krakow next week. I plan on eating the hell out of plenty of Polish food (even doing a cooking class) but NGL - I am CRAVING a good banh mi. A proper Vietnamese kick-me-in-the-face-with-chilli banh mi.

So my question to the brains trust is - will I find this in Krakow or do I need to wait for another city??
