About Local chocolate bar from Bulgaria

This is exactly the sort of thing I like bringing back from Bulgaria: small enough to fit in a bag, but specific enough to remind you where you bought it. Look for a boxed version with a decent date on it, especially if you are buying it near the start of the trip rather than at the airport. I would look for it in a proper local supermarket, covered market, deli, pharmacy, gift shop or small producer rather than leaving it until the departure gate. Back in the UK, it is worth checking specialist shops first because they often stock a better version than a broad marketplace listing. It is also the kind of thing you can talk about when someone asks what you brought back, because there is usually a little story attached to where you found it.
