There are a few places around the Kita-Senju area, and most do a run-of-the-mill lunch set. Bougain Villea stands out for two reasons. First, they do a biryani lunch set, which is quite a rare find if you are familiar with what most standard places offer. Second, when you ask for the hottest one they do, it really does leave a decent fiery remainder in the mouth, and certainly a lot better than the usual damp squib of a sensation in places where a 'hot' dish would potentially scare off customers.
