Uw tips:If you want a taxi, ask for one at the Information in the airport before getting out, do not accept to take a taxi from the drivers who wait at the exit, they will charge you 5 time more. Also look at the tariff printed on the taxi, different companies have different tariffs. The cheapest is 1.39 RON/KM Enjoy.
Bucharest is an old and cosmopolite city, with of modern architecture, some spectacular. The old villas in the downtown core have sublime architectural ornaments, some renovated some old and forgotten. People are nice and girls are fashionable, taxis are inexpensive and full of orthodox crosses and icons. Get advised by locals on restaurants, we recommend Nan Jing for Chinese and The Carul cu Bere, Nicoresti for Romanian food. Hanul lui Manuc is a beautiful place to have a beer but stay away from steaks - choose ethnic dishes or "mici" (kebbob-like). We went in June and the entire city is embraced in linden flower scent: it is sublime, I still feel in my nose that sweet, honey-like smell, it makes the entire city melancholic and fascinating. There are many churches and look for canvas painting exhibitions, visit the National Art Museum, and if lucky go to a concert at the Athenee. Be vigilant of modern looking gypsis who stair at your bags, nothing happened to us, but just stay vigilant, don't walk around with bags full of cash.
Airports and train stations are clean and civilized, also there is a nice Duty Free section in the airport Henri Coanda.
