In-N-Out Burger — Restaurant in Monrovia

Burger and shake were good as usual. Be prepared to wait in the drive thru for an unreasonable length of time. I counted 28 minutes from the time I entered the drive thru til I picked up my order. Oddly, I counted 4 traffic employees out in the parking lot trying to coordinate parked cars and drive thru traffic. This location lacked adequate planning and was not built for speed. I’m not sure if coming to this location during a lunch break would work out as there just wouldn’t be enough time. The Arcadia location on Santa Anita Blvd is my usual go to location. My drive thru wait at that location is about 10 minutes tops. The Arcadia location has 2 true designated drive thru lines, whereas this new location only has 1 drive thru line. Hopefully this In-N-Out Burger location can tweak a few things to make it a more enjoyable...

Store#425 @10am on 9/25/2025

...Finally open! My family and I live across the street, so this will be dangerous! Went in around 10am on the opening day and boy was it awesome!

This store is one of the coolest stores yet, it's very ergonomic like and will most likley be able to handle rush hours. Today for the opener, there is a lot of extra employees and everyone has been so very nice and welcoming.

(Edit: the merch tents were gone after the first opening day) There's merchandise tents outside in the parking lot, they will be out until monday I believe...better get some gear before it's gone! They said it will go fast!

P.S...Bring your electric vehicle and charge while you eat... there is tons of EV chargers...

I've been waiting 30 minutes in the drive-through line, but two cars behind me ended up in front of me because merging two lanes into one was not organized fairly. This incident happened when one of the staff members taking orders had a shift change, which also delayed my order. When I mentioned this to the staff members, one of them sincerely apologized (since he just began his shift and had no clue), but the other staff member told me she would push my order ahead. Please! I'm in the drive-through line! There's no such thing! Trying to trick a customer is not...
