Absolute best place in town. Drive-thru is very efficient and fast. Staff super friendly. It’s like a well oiled machine. Food is always fresh and hot. I’m from California and have been in Colorado since 2001. Happy they have finally opened restaurants in Colorado and especially longmont. The food tastes exactly like home.

Sometimes you just want a classic burger done right, and In-N-Out nails it every time. The hamburger is simple, fresh, and exactly what fast food should be. The bun is soft and slightly toasted, the patty has that signature grill-seared flavor, and the lettuce, tomato, and onion actually taste fresh—not like they’ve been sitting around all day.
The spread ties everything together with a creamy, tangy kick that makes the whole burger feel balanced. It’s not the biggest burger in the world, but the quality makes up for it, and it never leaves you feeling heavy or greasy.
If you like customizing, adding grilled onions or going “Animal Style” takes it to another level. For the price point and consistency, In-N-Out’s hamburger is still one of the most reliable fast-food staples out there.

I’ve been steadily going to In N Out and live near the 136th location and I must say the quality from service, cleanliness, and most importantly the food is A++ here versus any other location. In N Out is always great, but it’s above and beyond here. I work nearby and it’s always fast to grab a bite.

Convinced that anyone who hates on In N Out is a bot. Consistently delicious burger and taste and quality. Nicest staff, cleanest restaurant, etc etc stars on stars

The cheeseburger was very good but I didn’t particularly like the fries. No flavor and strange texture. Hamburger had a full slice of onion and tomato. Service was great and place was kept extraordinary clean. Shortest menu I’ve ever seen for a fast food place…3 choices of burgers, fries and soft drinks. I would go again just for the burgers.

The new In-N-Out Longmont is pure burger bliss. The moment you walk in, it’s “fresh, fast, flawless.” The Double-Double hits with that classic California crunch, and the fries are “sunshine in a basket.” Smooth service, spotless vibes, and a line that moves like magic.

What a sharp outfit and great service! It’s too bad that with all the hype that the food isn’t good. The hamburger buns are spongy, and nothing special. The french fries taste like the potato sticks that my grandma had in her cabinet. They should offer more sides like bacon with a cheese burger. The shakes were on the small side. I did like the cherry coke. No desserts the menu was a disappointment.

Not quite the burger I remember in California. I had the basic hamburger with ketchup and mustard (no special sauce), grilled onions and small fries. It just didn’t have that ultra-fresh flavor that the California restaurants had – crunchy lettuce, perfectly cooked patty. My burger tasted like it had been sitting for a minute or two or three. Great price! The fries were surprisingly dull, of all things, they lacked potato flavor. Employees seemed overwhelmed behind the counter – a good plan with clear responsibilities assigned would fix this. Employees in the dining room were scattered, some hanging out in the bathroom, some just chatting with each other, and some actually tending to customers. Employees need better training. Management needs to be visible and accessible. If everyone knew their role and completed their assignments this could have been much smoother. I love I-n-O and will try it again to see if it was just grand opening mayhem. I suspect it will get better.
