The wait is finally over for Monrovia residents.

A wave of excitement washed over the Huntington Oaks Center as the brand-new In-N-Out Burger officially opened for business on Thursday, September 25th.

Eager customers from Monrovia, Arcadia, and Duarte created a festive atmosphere, with cars carefully guided through the parking lot into the bustling drive-thru lane.

The restaurant, which sits on the former site of a demolished Black Angus, opened its doors 90 minutes early at 9 a.m. to welcome the first wave of diners.

It was a truly electric grand opening.

Company owner and president Lynsi Snyder was even on-site, accompanied by a team of company veterans to support the new crew on their first day.

The opening marks a significant addition to the local fast food scene in the San Gabriel Valley.

The impressive 3,879-square-foot building features indoor seating for 84 guests and an outdoor patio that can hold another 38 people.

True to the brand's heritage, the design includes the famous crossed palm trees, a nod to founder Harry Snyder's vision.

This location is the 425th restaurant in the beloved chain.

For those craving a late-night Double-Double, the restaurant will be open until 1 a.m. on weeknights and 1:30 a.m. on Fridays and Saturdays.
