If you eliminate the sit-down restaurants, pretty much all you have is the Katsura Grill in Japan pavilion. Used to be Sunshine Seasons had sushi in its grab and go area, not sure they have it anymore.
Thanks for all the quick replies. We're going tonight, so this is really helpful. We'll be walking from Epcot to HS around dinner time
Do sny of these places just have plain sashimi?
Kimonos is the only one that might have sashimi. I'm pretty sure you can ask for carryout, but it's not a counter service place, don't know how long you would have to wait.
We had really yummy sushi during F&W at the Japan kiosk, not sure when your trip is. Otherwise, if they had it during F&W, I'm sure what they normally have is equally good.
