There is no way to tell you whether or not you'll like it. I can tell you that I hated it and everyone I know IRL to try it thought it was greasy, fatty, and disgusting. How's that for honest?

It was dripping in grease and loaded with sugar. Blech. There are a few people on here that don't care for it, either, I've found - you can do a search. I took 3 bites and felt icky. DH ate about half, he's the one who LOVES sugar, but felt ill the rest of the morning. It's very heavy. My DSis made the mistake of ordering it a few weeks ago on her trip and picked a couple bites at it and had the waitress take it because she couldn't handle even looking at it.
My advice is to share it between a few people so everyone gets a taste. I can't imagine how anyone can eat it for their entire breakfast, personally, but can see if you like super sweet, greasy food that you could eat part of it with the rest of your breakfast. Or maybe there are stronger people than me out there, LOL!
We enjoyed breakfast at Kona but did not enjoy the beloved Tonga Toast. Since you'll have tons of people come tell you how much you'll love it, I wanted to give my opinion since I thought I would love it too... I ordered it because of the reviews on here.
Just goes to show that there is something out there for everyone! =)
