Taiwan. Home to the first Hello Kitty-themed café, Hello Kitty-themed airplanes and now - taking cute perhaps one step too far - the world's first Barbie-themed restaurant.
Licensed by U.S. toymaker Mattel, Taiwan restaurant company Sinlaku on Wednesday opened the Barbie Café on Zhongxiao road, one of the busiest shopping districts in the capital, Taipei.
The café's decoration, costing TW$50 million (US$1.7 million), is mostly in suitably Barbie-style magenta and pink.
The furniture couldn't be more princess-y - bar tables look like the heel of a stiletto, chair backs resemble bustiers (some with a tutu) and chandeliers are shaped like elegant teapots and teacups with saucers. Barbie dolls and logos adorn walls and tabletops.

Hello Kitty fans might be the world's most spoiled travelers as the tourism industry seems determined to build a complete service chain out of that five-apple-tall bobtail cat.
Taiwan's Eva Air flies a fleet of five Hello Kitty airplanes. Dubai houses a posh Hello Kitty spa. Anji, a county some 220 kilometers southwest of Shanghai, is building a $200 million Hello Kitty theme park (scheduled to open in 2014).
And in Beijing, a Hello Kitty-themed restaurant is creating a lot of buzz.
