I like popping in here when it's mid-afternoon and I missed lunch, but it's also a lifesaver for those very late almost-to-dawn revelries. There are branches across the city, including Shinjuku, Ikebukuro, Ueno, Akihabara, Harajuku, and Ebisu, each with its own decor and opening hours (check the website for specifics). This one is dark, with decorations that might confuse the inebriated (like fish swimming in a repurposed birdcage) and distractions like personal-size TVs at counters and tables showing Kohmen commercials, concerts, and film previews. The black-clad staff delivers steaming bowls of ramen swiftly, with the English-language menu listing options like thick, thin, or crispy noddles, various broths (the basic soup is made from stewing pig and chicken bones for up to 12 hours), and extra toppings like grilled pork. I like the kagashi-tantanmen (a creamy sesame soup with noodles, hot chili, and char-grilled marinated pork) so much that I've never tried anything else, which is highly unusual for me.
