I wanted to point you to an excellent post made by Pomai from The Tasty Island a little while back.
Pomai – with some help from his readers & friends – put together a list of Oahu eateries which are 50 years old, or older.
Will you like to visit any of those on your trip? There are two on my list for certain – I won’t mention which two in case it doesn’t work out and we don’t make it there!
The good thing is though they might be established over 50 years ago, many of them have embraced the internet and have websites where you can read the menu ahead of time while sitting at home in Australia or wherever else you might be, and consider whether you will enjoy eating there and what you might choose from the menu.
