For some East Coasters, introducing their parents to In-N-Out means booking a flight to California.

But for food influencer Grace Lewis, it meant building an entire knockoff drive thru at her New Jersey home.

The content creator behind the wildly popular Crazy Korean Cooking page stunned millions after transforming her front yard into a convincing replica of the beloved West Coast burger joint — complete with a drive-thru lane, menu board, uniforms, burger wrappers, and ever a speaker box — so her parents could truly take in the full experience.

Lewis, who has 2.1 million TikTok followers, racked up 5.3 million views on her video detailing the process of reverse engineering the menu, the merch and the branding.

With some help from her sister, Lewis ground the meat, made ketchup and thousand island sauce from scratch, whipped up homemade American cheese, baked burger buns and more — all at home.

The pair donned replica uniforms, printed custom cups and wrappers, and to avoid potential trademark issues, the renamed the pop-up “Out-N-In.”

At the “drive-thru,” her parents ordered a Double Double Animal Style, 4X4 Animal Style, french fries Animal Style, a Lemon up (pink lemonade + 7-UP) and a vanilla milkshake. When her Korean parents pulled up to the “pick-up window,” they received their food in a classic red tray, with their food in the traditional palm tree wrapping.

The painstaking recreation had social media users eating it up as fast as Lewis’ parents ate the burgers.

“This is the cutest thing I have ever seen,” one TikTok user commented. “Genuinely this family brings me way too much joy,” another added.

Others flooded the comments section saying her In-N-Out dupes look superior to the real deal. “As a West Coaster who loves In-N-Out, you nailed this,” one person wrote, giving their seal of approval. “I bet yours is even better.

Lewis said her parents have unexpectedly become the breakout stars of her social media channel, with viewers falling in love with their wholesome reactions.
