Have a look at the picture below: what do you see? Nothing? Try again. Still nothing? Don't worry: this is a photo of an establishment that I initially managed to walk past three times, convinced I'd got the wrong address. Tucked away in a nondescript street not far from the rue Neuve, surrounded by office blocks, Sakagura - a.k.a. possibly Brussels' most anonymous restaurant - is unlikely to be a candidate for much walk-in custom.
