Hi Jennifer!
Thanks for bringing your question to the Disney Parks Moms Panel. Disney's Polynesian Village Resort is one of my favorites on property and my family and I often dine at
Kona Cafe during our stay!
You are certainly correct that there have been very recent changes to the
Kona Cafe Menu, as early as within just the past few weeks! The menu you find online currently does reflect these changes, which is why some dated reviews may no longer seem correct. If you want to look online, you'd need to look for reviews that have come out from mid-January 2019 and later. One blogger I found that went just to check out the changes raved about the Fire-Roasted Pork Wings!
For any type of allergy, please just notify the Cast Member serving you that you have a
peanut allergy and they will certainly work to come up with some alternative options that may not be listed or changes that can be made to current entries to ensure a safe dining environment for you. Walt Disney World Resort really goes above and beyond to ensure the safety of their Guests dining with any type of allergy at any restaurant across property.
I hope this helps in planning your upcoming visit! Please come back and visit if we can help in any other way.
