A gust of wind nearly blew you off the Eiffel Tower—time to warm up with a bowl of ramen at this tiny step-above-casual spot full of office workers and in-the-know tourists. You have a choice of three chicken-based broths and a vegan option, though it’s hard to beat the chef’s special sakaï, a favorite since the mini international chain’s founding two decades ago. The seven-hour chicken broth is topped with chicken breast and duck slices, plus minced red onion, chive, and precisely two bits of grilled onion for a smoky, barbecued-like flavor. You should level it up with the €2 extra soy-marinated egg with creamy yolk.
