We hear the Oki Diner is a local favorite. You choose your meal mostly by the picture. Older-style coffee-shop atmosphere, but don’t be scared. Some things on the menu we did not know, ie, Loco Moco, noodle dishes, etc. I overheard the spunky (70ish) waitress suggest to a young man that what he ordered was so-so and strongly suggested he try something else.
The breakfast was great, pancakes especially. The move the creamer and syrup from one table to another. The macadamia nut pancakes are delightful. The syrups are homemade: coconut, vanilla, and strawberry, no maple – so you’ll live. My husband had a fish (mahi-mahi) sandwich, which was also good. The Oki Diner does not accept credit cards (I don’t know about traveler’s checks), so it's best to have cash.
If you’re chicken, there is a McDonalds next door, but I would give the mac nut pancakes a try. Be brave and try a Kauai original.
