Beware In Kona....
I just returned from 9 days in Hawa'ii and had a spectacular time for the most part.
While staying at the Hilton Waikoloa Village we went into town (Kona) our second morning there and ate breakfast at Denny's. I became violently ill with food posioning about 5:00 p.m. and remained pretty sick for 7 hours after that.
I am pretty positive it was from the food at Denny's because the last time I ate prior to that was 8:00 p.m. the night before. Please be careful, I would hate for anyone to become as ill on their vacation as I was. It was pretty frightening. I reported the incident to the Hawa'ii health department and was sent to a hospital for testing, to determine what exactly made me ill.
Denny's of course accepted zero responsibility, but did offer me a free meal (just what I wanted). Be careful out there!
