The 24-year-old actor said he likes being in the city, reported Contactmusic.
'Anyone who equates 'coolness' with a lack of enthusiasm is just very, very irritating to me...New York is a great city," Radcliffe said.
"It has an incredible energy and it is very positive. I think in England we sometimes make fun of Americans for being so positive but I am actually all about that. I love enthusiasm," he added.
