My favorite snacks (try whatever sounds good). Its a lot, because I go really often, so I rotate through these all regularly. Most aren't new, but some are "seasonal."
Disneyland:
Matterhorn Macaron-JH Bakery
Raspberry Rose Macaron-JH Bakery
Chocolate popcorn-Kat Sakas Kettle (you can get all one flavor even if there is only a blend on the menu)
Pork Lumpia-Tropical Hideaway
Dole whip, but at Tropical Hideaway, not the Tiki Juice Bar (more flavor and swirl options)
Onion Rings from Hungry Bear
Potstickers from Lucky Fortune
Cheese stick from Corn Dog Castle
