…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 available.
Enjoy!

Very nice. Brand new in and out with a huge dining room and a very well organized drive-thru. As always, staff is trained well and it’s very clean and friendly!

One of the best damn hamburgers and animal fries in the world and the east coast only wishes they have In-N-Out this good and pretty soon the corporations are moving out of California to Tennessee thanks to Gavin Newscum and Karen Bass!

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 nice at all!

The best burger in SoCal, bar none. My go-to is the Double Double with whole grilled onions, raw onions, and chopped peppers. Their fries are also one of the best in the industry. No ketchup, just salt. Strawberry shake or pink lemonade. One of the best meals around and the best price. Can’t beat this!

Foods always right as I’ve never gotten a wrong order before. Price is cheaper and the most fast food places. Parking lot is set up nicely tho the 2 lane drive through needs a little work

I was guest #125 on their second day in business. I cannot say enough good things about my experience! Firstly, the traffic control was very well organized and executed. The ordering process through receiving my food was great. The In-N-Out employees seem very well trained. They are very friendly, polite, cheerful, and efficient. The food was exactly what was expected and cooked to perfection. Kudos to the Monrovia In-N-Out Team for a job very well done!!

Good quality food is why In n Out keeps growing. If your really hungry, oder the 4×4 (4 pattys and 4 slices of cheese), grilled onions, well done, and protein style. Clean, friendly employees, and usually busy, but worth the wait.
