The Seaport locale of this London-based chain offers seating at long communal tables with an upscale industrial vibe. Some prices are a bit steep—$18 for ramen—but portions tend to be large, and the bowls are packed with fresh veggies and your choice of protein. Stumped by the vast menu? A good go-to is the ginger chicken udon, which has chicken, snow peas, egg, chilies, bean sprouts, pickled ginger, and cilantro atop chewy udon noodles. There's also a convenient outlet in the mall that's attached to the Hynes Convention Center.
