Tantanmen is a direct descendant of Chinese dandanmein. This dish of Sichuan origin is spicy, and a traditional bowl will have plenty of chili oil, Sichuan peppercorn, and minced pork. You can find tantanmen at many Chinese restaurants in Japan, but for the best bowls, you have to go to shops that specialize in the dish.
Lashohan is one of those shops. They serve nothing but tantanmen, though they have a few varieties. The Masamune Tantanmen (Y850) is a classic soupless style, but for fans of the bitter-hot Sichuan peppercorn, go for the Premium Masamune Tantanmen (Y1000). It is full of spice, peppers, and flavored oils, though a bit of an overload for the uninitiated.
If you want tantanmen with soup, they offer a few varieties. The menu is easy to understand, with plenty of photos of the bowls.
