Delicious. Coming from the East Coast eating here is always a treat. Very efficient staff .

Double-double, extra toast , with pickles , grilled onions , and spread is love. Double-double, extra toast , with pickles , grilled onions , and spread is life.

Love In-N-Out. Go there and you know what to expect. Went in to order fries instead of waiting in long drive thru line . I was "In-N-Out" in 5 minutes... Maybe less!!!

This was my first time eating In-N-Out and I gotta say: I’m still the same person! My worldview did not fracture! It’s a cheeseburger !

Good for a late night snack when your plane gets in late from the East Coast.

Yummy. Make sure u ask for a Neapolitan shake . Not on the menu but it is chocolate ,vanilla , and strawberry .

Try getting your fries "animal style " (with special cheese sauce and caramelized onions ), not on the menu ???? Your welcome!

FAST DRIVE-THRU, friendly greeters that take your order. Fresh hot burgers and the best in-n-out fries I've ever tried.????????????❤️????????????

Absolutely MARVELOUS food! Next level burgers in a classic surroundings!

If you are double dipping with the car wash across the parking lot , hit In n Put first, as there are lots of birds around the overhead power lines and they shit everywhere. You're welcome.

Convenient location near the airport . Great first stop for all of your out of town guests to sell them on SF.

Probably closest In-N-Out to SFO & brand new to boot. Take Millbrae exit off 101 & you can't miss it.

Close to the airport . Animal Style & Neopolitan Shake is a winner

Order a double double animal style , animal style fries , and a neopolitan shake . It's the only way to go... So damn guuuuuud when your buzzed.

Double Double Animal Style with extra Spread is unreal. Don't care for the fries at all though.

Stop by before a flight, or during a long layover, to experience a California classic.

Animal style with chillies and whole grilled onion . Plus a Neapolitan shake !

not sure why west coasters love this place so much. give me shake shack any day! no mayo ? $2 extra for cheese on fries ?

Do some research on the secret menu in advance. Cal horrific but you have to try once. Over hyped, but exceptional value and they really care

Definitely better than the Daly City location.

Eat here then park at Aloft hotel on flights out of SFO. Super convenient!

Go to an In-n-out, authentic california burgers . There's one on fisherman's wharf, but it's not as good as the one in millbrae. Still better than nothing.

The closest double double to SFO. Also perhaps the only "Bartable" In-N-Out (Millbrae)

Try the Double Double Animal Style Cheeseburger With Fries - (via @Foodspotting)

Get a double single if you think a double double is too salty with the double cheese

Since you just landed after a long flight, stop by this awesome burger joint - you can't find it out East and its too good to miss!

Double double ! Google for the secret recipe before going to the store.

Burgers are so juicy !

Ask for spread for your fries instead. It's a nice alternative to ketchup .

Double double ???? and animal style fries ????

Ask for extra well done fries , you won't regret it.

I always get the double cheeseburger and animal fries !

If you from anywhere we dont have In-N-Outs, then you have to go here. Love there food, love there service!

What is this cardboard doing on my plate? Ohh this isn't called cardboard, what fries ...yes please I have some...oh these are the fries . Wow why? What have the potatoes done to deserve this?

Look out for Animal Fries .. It's a hidden menu ;) ;)

Make this your last SF pit stop before heading to SFO. Yes, you can bring burgers through security

Double double and the secret menu is the finest

Protein Animal Style is wrapped in lettuce, I get it without the cheese and get my hamburger fix and stay healthy

Good place near the airport . Cannot go wrong

It's great for a late meal on weekends when you're out with friends. They stay open late

Long line but worth it for burgers and milkshakes !

Try the 2 Double Doubles With Fries - (via @Foodspotting)

Double meat, no cheese protein style . Perfect paleo meal.

Don't just get any shake . Get Neapolitan (all 3 flavors in one)!

Cheese burger grill onion protein style (lettuce wrap no bread ), animal style fries & chocolate shake - guilty yet delicious!

Everything here is good

Friendly staff members, efficient services and clean facility

Animal style is the way to go!

The line is always (always) long here - plan accordingly flying buddies

Best burger
