We paired up with specialty food purveyor Regalis Foods to bring real black truffle to select Los Angeles and New York City Shacks for a limited time! Founded by Ian Purkayastha and based in NYC, Regalis is known for providing luxury, tough-to-find products including fresh truffles, rare foraged edibles, Japanese wagyu beef, caviar, uni, and live exotic seafoods.

Meet our Truffle Menu, featuring three new items made with Regalis’ USDA Organic Black Truffle Arbequina Oil, the only truly natural truffle product on the market, made from Spanish black truffles and California extra virgin olive oil:

Black Truffle Burger

Cheeseburger topped with real black truffle sauce, gruyere-style cheese, and crispy shallots on a toasted potato bun

Black Truffle ‘Shroom Burger
