K-Town, a highly concentrated strip along Manhattan's West 32nd street, between Broadway and 5th Avenue, is a slice of Seoul in the city, and officially known as "Korea Way."
It features dozens of Korean restaurants, karaoke clubs, and even 24 hour spas, most of them stacked on top of each other thanks to the narrow borders of the area.
New York is home to over 140,000 Korean residents — the second largest Korean population in the US — and while they may not all live in Koreatown (many live in Flushing, Queens, another Korean hotspot), they do frequent it enthusiastically, giving the area a super local and authentic vibe.
While there's always a debate as to where the food is better, Flushing or Manhattan, K-Town is steadily gaining a stellar foodie rep.
