Hi, Jennifer!
I'm not sure when your travels are bringing you to Walt Disney World® Resort, but Kona Island Coffee & Sushi Bar located near Kona Cafe at Disney's Polynesian Village Resort is currently closed for refurbishment until October 1st, 2014.
If you are planning to visit after this time, you'll find the following hours and offerings for this casual location:
Coffee & pastries are available from 6:30am- Noon.
Kona Island is closed daily from Noon-5:00pm.
Sushi, Sake & Wine from 5:00pm- 10:00pm.
If lunchtime sushi is what you're after, I suggest giving
Tokyo Dining in the Japan Pavilion at Epcot® a try. Here, you'll find the most extensive offering of sushi options available.
Another option for lunchtime Sushi is
Splitsville Luxury Lanes™ in Downtown Disney. With dining options available without the bowling, popping in here for sushi is an excellent alternative.
I hope this is helpful, Jennifer! Please do not hesitate to reach out to the Disney Parks Moms Panel for any additional questions you may have! We are here to help.
Happy Dining!
Faith D.
