Ramen is the ultimate comfort food, and here you can choose from over 20 varieties thanks to Okinawan chef Hisashi Uehara. His team makes all the noodles from scratch and boils 2,880 pounds of pork bones daily for more than 24 hours to create the chain's signature tonkotsu broth. Agu has seven outlets across Oahu, including one in Waikiki (2146 Kalakaua Ave.). Slurp your way through specialties like Parmesan cheese kotteri (an extra thick, oily broth) or a chicken-stock mix with citrusy yuzu and pepper. Additional toppings include house-made chili, pickled mustard greens, and pork belly roasted Cantonese-style, like char-siu. Vegans and vegetarians: Ask about your options, as they're not well-labeled!
