If you're visiting the REI Flagship store and you get a hankering for a burger or shake, I recommend a visit to the Lunchbox Laboratory. Our burgers and shakes were super yummy! Burgers came with a pickle and side of tater tots. Talk about nostalgia! The kids' Mac n cheese is no Kraft. It's the real deal. The ambiance was pretty cool, too. Lots of nostalgic feelings eating burgers and drinking shakes while surrounded by classic metal lunchboxes.
Had a lot of fun customizing meals, the waitress and staff were prompt and friendly despite being under staffed. Good food and great staff.
Honestly one of the best burgers I've had, like wow super flavorful and good sized. I don't think I would recommend the garlic version of any of the sides unless you really enjoy garlic, it was a little much for me but that's a nitpicky thing. The atmosphere is very cool and kid friendly. Also their shakes are delicious.
I'd heard of this place before and decided to stop in while in town for Seafair. It wasn't busy for lunch on a Saturday, but I'm sure it gets busy at night. Great place to take the family, or after work. The menu could be a little overwhelming for the indecisive. I got the cod sandwich, which was probably the best one I'd ever eaten. The best tartar, too. For my fries, I did the rosemary and cinna spice, which I also highly recommend, and you can thank me later.
We found it on Groupon the reviews were good oh my God some of the best food we have had in Seattle. The hamburger Was Juicy loaded with extras and it also came with your choice of fries or tater tots which is a homerun. We had fried pickles as an appetizer and a few of their specialty drinks that came in scientific glasses which were out of this world highly recommend this place we are from New York so if we like it you'll like it come one come all
Super fun place to eat. Has a great selection of Kobe beef Burgers and shakes from Umpqua Dairy. A highlight is all of the assorted salts. Bacon salt, garlic salt' Rosemary salt Etc. Easy parking. Knowledgeable staff. Fun decor your eyes are very entertained while eating. Food was great I had fish and chips and there was actually a lot of fish and a little bit of breading which made it great. Hubby had a burger that was seriously 4" high had to deconstruct to eat it. He loved it! I had a mint chocolate shake absolutely delicious. I would recommend going there for lunch. A bit pricey. Not your fast food burget for sure while in Seattle.
It was a 23 minute walk from the museum of pop culture but so worth it. We all tried different things, the only miss was the veggie burger. The milk shakes, tots, cheese curds and the other food we got were great. The Staff was friendly.
Zane was a excellent waiter and very attentive. The burgers are unique, in a very good way. The happy hour food is a tad small in terms of portion, but still a decent size. Overall, glad I stopped by, will likely come back again.
Delicious, funky food. This place has some cool items on the menu as well as "experiments" on their special menu. The portions were generous and the servers were polite and offered some great recommendations. Definitely recommend checking this place out if you want a unique twist to the familiar.
Our Uber driver introduced us this place and it was absolutely GOOOOD!! Everything was so fresh, the food was tasty and the side were all yummy. Besides their burger, we also ordered Cod fish burger which was even better than regular burgers they had. The brussel sprouts were sooooooooo good and I never imagined it could be that delicious. This is definitely going to be a 5-star if you like burger and regular American fast food.
