Shake Shack and Avocados From Mexico are serving up a campaign that’s sure to delight avocado fans across the U.S.

Guests who order any sandwich or burger with avocado will have the opportunity to select their own fruit via Shake Shack’s Avocado Expert and receive a tableside slicing demo. Here’s how it works:

• When a guest orders an avocado add-on at select Shacks in NY, PA, FL, TX and CA on April 25 and April 26, they’ll be greeted by an on-site Avocado Expert in a special uniform who will present a selection of avocados to choose from (like a sommelier).
• The guest will choose whichever avocado they’d like.
• The Avocado Expert will slice it in front of them, then add it to their order.

For those without an Avocado Expert at their local Shack, Shake Shack and Avocados From Mexico are offering a FREE avocado add-on when guests order a sandwich or burger in-Shack or via the Shack app or website from April 25 through April 28 (terms & conditions apply). Avocado lovers can also enter to win a FREE trip to New York City for an exclusive visit to Shake Shack’s Innovation Kitchen, the hub of all menu development at Shake Shack, and enjoy an exclusive avocado menu courtesy of Avocados From Mexico.

Shake Shack and Avocados from Mexico are educating Shack guests on why using only the BEST ingredients is important and what makes avocados so delicious and nutritious. The beloved fast casual chain serves delicious food made with premium ingredients, and its avocados are no different – they’re freshly hand-sliced in-Shack every day (no prepacked “spreads” in sight). Fresh Avocados From Mexico contribute good fats and nearly 20 vitamins and minerals to your diet – making it the perfect add-on to any Shake Shack favorite.
