Everything in the touristy Waikiki is designed to scorch your wallet, but Marukame Udon does it most gently: each bowl of udon sets you back only around 5, which can be even cheaper than Coconut Cafe’s shave ice! This bukkake udon in cold broth is only 3.75, and it’s good, especially to give us some relief from the heat and humidity. Granted, because we add the goodies, the ticket goes up fast: shrimp tempura is 1.75 each, sweet potato tempura is 1.25 each, etc. What’s even better is the self-serving, cafeteria style: grab a tray, place your noodle order, take noodle, grab a few tempuras, pay, find a seat. Fast, efficient, and no tip.
