I lived in Ulaanbaatar for a year. Be careful, it's the most dangerous place I've ever lived. People are racist as fuck too. I've had beer bottles and shit thrown at me by drunk skinheads.
Oh, and nazis are an actual thing there. Like, Asian dudes in SS uniforms looking for foreigners to beat up.
Living in Ulaanbaatar is like living in Mos Eisley spaceport.
I love Mongolia and Mongolian language, but next time I go I'm going to spend as little time in UB as I can.
