The Waikiki area of Honolulu is notoriously expensive. If you're staying or spending the day in Waikiki, you'll be hard-pressed to find delicious, affordable food. As Waikiki was home-base during my trip to Hawaii, I did research on good eats in the area with a reasonable price tag. Based on the rave online reviews and my experiences, I believe Marukame Udon is the undisputed winner in that category!
For almost five years, Marukame Udon has been serving up the best bowl of thick, chewy Japanese-style wheat noodles or udon（うどん）in Waikiki. The noodles are made fresh to order; in fact, thanks to the restaurant's open kitchen, you can watch the chefs make them as you wait in line!
