The team behind The Peached Tortilla is bringing a new White Castle/Krystal-inspired slider pop-up to Austin. In addition to sliders - dubbed as “fat stacks” - they also have chicken tenders, fries, and tots. And for dessert (or dinner, you do you) they have “fatties” - marshmallow or chocolate cream-filled spongecakes that sound an awful lot like gourmet Twinkies. You can see the full menu and updates on their next location on their website.
