This is an easy to read, concise phrase guide that I would recommend to anyone travelling to Bulgaria. Not only does it include numerous Bulgarian phrases written in Cyrillic but also the direct English pronunciation.
It covers all your basic holidaying needs including topics such as accommodation, transport, food, shopping and emergencies. It also includes an English-Bulgarian and Bulgarian-English basic dictionary.
Plus it's got lots of little hints and tips on Bulgarian culture which adds a nice touch.
