This Kabukichō spectacle has hit it big with its vision of 'wacky Japan': bikini-clad women ride around on giant robots against a backdrop of animated screens and enough LED lights to illuminate all of Shinjuku. You can book ahead online (at full price) or save up to ¥2000 per person by purchasing at the venue with a discount flyer (available at Tourist Information Centers and hotels).
The show receives mixed reviews: some love it (you'll get great photos), while others recoil at the price and tourist-trappiness of it. You can have a small, free taste just by basking in the glow of the exterior, where two robo-glamazons are parked outside (also great for photos).
For the full experience, head to sister bar Ren after the show; it's in the same building, but the entrance is in the back.
