This is an incredible place by virtue of two shops which will complete the avid health enthusiast - Veganerie bakery, close to Gourmet Market; and Q Stadium, where you’ll be able to buy authentic running shoes and apparel such as those produced by Mizuno and ASICS. Q Stadium is over two floors.
There’s also a Kinokuniya bookstore but I haven’t been able to find that yet. This points to a problem I have with this rambling, but at night spectacular shopping complex, which is its confusing layout - despite the imprecise information boards on each floor. It took me maybe 40 minutes to find Veganerie.
