The subtitle says:
Restaurants and food in Hawaii (inc. Honolulu, Oahu, and Maui)
To someone who lives here it looks kinda ridiculous, to visitors it is probably confusing. Maybe something more like:
Restaurants and food in the Aloha State including the islands of Kauai, Maui, Hawaii, and Oahu (with Honolulu and Waikiki)
I think you can get away with leaving off Molokai, Lanai, and the lesser islands. No one here is likely to be asking about food on Kahoolawe or Niihau. The Aloha State is our official nickname so thats ok too.
If thats too long maybe you could get away with:
Restaurants and food in Hawaii (inc. Honolulu/Oahu, Kauai, Maui, and Hawaii)
