The Lan Kwai Fong area consists of over 400 businesses including restaurants, bars, shops, galleries, salons and more recently Initial Boutique, Haagen-Dazs and the soon-to-open Hard Rock Café.
Fluid will kick off an extensive marketing campaign which will encompass online, custom publishing, social media, print and an email membership sign-up campaign to its database of over 30,000 Hong Kong residents.
A new Lan Kwai Fong website llovelkf.com will go live in mid February along with magazine title Lang Kwai Fong Insider, launched in April.
"Our target audiences are the original fans of LKF, who are mostly affluent and hip crowds who like to go out to have fun," said Simon Squibb, MD of Fluid Hong Kong.
"One of our main challenges is to make people realise that what's going on in LKF is not just the bars and restaurants on the street level, but also the upstairs retail outlets, cafes, galleries and salons in the neighbourhood."
