Hamamatsucho 1-28-4. Open 11:30am-2:30pm. Closed Sundays.
Serving very good ramen by day, in the evenings Zoot turns into a comfortable wine-bar/bistro. The shio ramen with egg comes in a chicken-based broth, with fried garlic chips, croutons and a lemon slice; there are also a variety of tsukemen dishes.
