Idaho's first In-N-Out location has proven that a good business can repeat quality food and great customer service in a new place! This was an uncomfortably busy restaurant when they first opened, but now there are times when you can walk right up and order with no line. Sure, it's 10:30 AM, but it is there for the people who want an early lunch and don't want to wait in line! They are also planning a Nampa and Boise location, which will take some pressure off the Meridian restaurant. I recommend the double-double with whole grilled onions, and animal fries which come with melted cheese, spread, and grilled onions. Their shakes are thick and delicious. You can't beat the price for this quality of food- cheaper than McDonald's and way fresher ingredients. They hand-cut the potatoes on site! And everything is made to order. If you want to dine in, plan to go at off times (early lunch, early dinner, late at night). They run their drive thru line efficiently and you're always moving.

Always a long wait, but worth it. Consistently delicious. Your typical in-n-out experience.

Early lunch with my better half, her first time! What a great spot, awesome food at the right price with great service, totally makes sense why this is an American establishment. We ate inside, had our order in and were eating within 15 minutes. Love that we have one in the valley now!!

It's In N Out How can you go wrong? The double double with grilled onions is the best.

I have had In N Out once before in California, so I was excited to see they opened up a spot in Idaho. The inside is super cute inside with a lot of tables. Every single table was taken! The line to order wasn't too long but it did take a while to be ready because there were tons of customers. I ordered cheese fries and a cheeseburger. My husband ordered animal style fries and a triple cheese burger. The burger was pretty good and tasted fresh. The only reason this is a 4 star is because the fries were good but a little cold. I still liked them a lot. I did eat the burger first so I believe they may have gotten cold because of that. Overall the service was good and the food tasted great. I was surprised how fast it was considering it was super busy inside.

My burger was a bit cold and fries were not the best. I was still eating it, and then I finally got to a portion when the burger was tasty and perfect! It's pretty good. The line was so long, but we went inside, met some new friends and got our order. It was perfect! We continued to spread the word the following day about there being an in and out. Let's just say the next few days, the lines were longer!!! (I'm uncertain is still why seattle doesn't have one, or tacoma, or Lynnwood.) The lines can get long when burning gas, wasting time, and more, so maybe you should park your car and go inside!!! (After writing this review I found out there was a 5 hour wait the weekend we went. To be fair, our event had over 10k people, so I'm sure our events attendees had something to do about it ) Alll the business were thriving that weekend and this place was one of them! Glad I got to go!!!!

Finally got my In-N-Out fix. Saturday morning at 9:45, no line and a handful of people already at tables. It was about 12 minutes before I got my food. Very clean restaurant, but one of the smaller ones I've been in. Wonderful customer service, both at the counter and helping out in the dining area. Employees were offering to get people's orders for them or chatting with a few regulars. Maybe not a typical breakfast spot. But I'd consider it a breakfast of champions! Drive-thru line didn't seem too long and looked to be moving pretty steady. By the time I left (10:10am-ish) the dining room was getting full. But still only a few people in line.

I've waited more than 50 years for In-N-Out to come to Idaho. And for good measure I was part of a group of fans who camped out for more than 21 hours in the cold to be among the first customers at this location. Back in 2020, In-N-Out announced it would open its first Idaho restaurant within five years. And with the opening coming on Dec. 13, 2023 -- the California company's 400th store, they crushed their timeline. Unlike nearly every other burger chain, In-N-Out butchers its own meat and keeps all of its hamburger patties fresh. Their stores do not contain any freezers, ensuring the meat and produce remains fresh. I've now eaten at this restaurant twice and the burgers taste every bit as good here as the numerous locations I've visited in California, Utah and Nevada. Nothing is prepared until you order and it's piping hot when you get served. In-N-Out's menu has changed very little since the company was founded in 1948. They do one thing and they do it very well. The well-known secret menu allows you to customize your burger to the way you want it. I recommend getting your burger animal-style, in which they slather mustard on the patties on the grill, add pickles, an extra dab of their thousand island "spread" and grilled onions. I ask them to add chopped chiles, a whole slice of raw and grilled onions and sometimes cold cheese. Standard is cheese that melts while the patty is cooking. Many people complain about In-N-Out's fries. Personally, I think the standard fries are not cooked enough. I ask for them "light well." That adds about 40 extra seconds in the oil and makes them much better. You can also order fries well done or even light. I love a neapolitan shake, where they combine vanilla, chocolate and strawberry. Or ask for a root beer float. On the pop side, I like to combine lemonade and &-up, a lemon-Up. Service is stellar and has been a hallmark of In-N-Out since its founding days. Rule No. 1 is the customer is always right. If there's a problem, Rule No. 2 is consult Rule No. 1. They want to make everything right. So if something is off, let them know. They'll take care of it. With any In-N-Out opening comes long lines. Super long lines. My advice is to get there early, before the lines start forming. Although the stated business hours show a start time of 10:30 a.m., if they're ready they'll open the doors at 10 and you're free to come in and order. Today, on the second day of operation, they opened for business at 9:30 a.m. It's a great company. They pay the highest wages in fast food and offer employee benefits. The next two Idaho locations are planned for Boise and Nampa.
