Oh, for me it has to be this awful soup we were served one time we were in Riga. It smelled like a compost heap, looked like a compost heap and (unfortunately I was forced to taste it as well) it tasted what I imagine a compost heap would taste like. Worst of all? EVERYONE else around my table loved it and claimed it was the best thing we had been served while we were there... Contenders for second place would have to be the weird grey goop we were served one of the other days (at least that the others agreed tasted awful), oh and garlic bread is pretty awful for me...
