As you might have expected, we eat out a lot when we do research for our Prague food tours, the Prague Foodie Map and this very blog. (Hey, we have an Instagram account and we try to post a picture a day, which means a meal out a day. Yeah, it’s hard to be us.) But in doing so, we often see foreign visitors do things that clearly identify them as foreign visitors and set them apart from the locals.

So we have investigated the phenomenon, asked around some of our favorite restaurants and came up with a list of “Czech food fails”: things done to Czech food by foreign visitors that make the locals either shake their head in disbelief or straight out cringe. Here’s how you don't eat Czech food in Prague restaurants.
