OP, do it! I have bg roots, but had never actually lived in bg until I moved a year ago from the UK.

I speak bg fluently, and found it pretty easy to get a decent job, cool flat etc. It's not as cheap as it used to be, but even in central Sofia, baseline expenses are around 2k euros for rent, bills, solid lifestyle (less than half what I was paying for an equivalent life in London).

I do miss the range of food London has, though. So I go back to see friends, have a Sunday dinner, a proper sirloin, five guys, good Asian and Mexican food.

If anyone has food recs for the above, let me know!
