Fantastic trip report, glad you enjoyed Bucharest. I was there this time last year and loved it - Lipscani (the old centre) is great at night, so many bars. And the women - my god they are beautiful!
I think we ate falafel wraps in the same kebab place and also the one opposite which you said could have been closed - great food from both places! Great food everywhere really.
Also good info about the taxi machine at the airport, didn't know about that. We walked all the way round to the departures and picked up a taxi that had just dropped someone off and was just as cheap.
