Mercury’s Coffee

The Bee’s Knees was great.

My Daily Go-To Spot with the Friendliest Staff

I absolutely love Mercury’s Coffee Co. in Sammamish! I’ve been visiting every day for over a year, and every single person working there is incredibly humble and friendly. Even the new team members fit right in with the same welcoming vibe. It’s more than just great coffee — it feels like a community where everyone knows your name and treats you like family. If you’re looking for amazing coffee paired with genuine, kind service, Mercury’s is the place to be!

Had a pretty bad experience the last two times I came to this specific location. They didn't have the mobile order ready so had to wait for 10 mins behind all the cars. They had no idea how to charge the mercury card on the local app. And when asked to use decaf instead of caffeinated espresso in the chocolate smoothie I was told they didn't substitute.

As soon as my gift card runs out, I will stop coming to this location.

I love Mercury’s coffee so so much! They never disappoint. Great staff who deliver an absolute top-notch roasted coffee every time!

Mostly a drive through but you can walk up. The staff is incredibly friendly

I ordered a coffee and burnt my tongue… not necessary to make a coffee that hot. Not drinkable for over an hour. Literally scalding. I’ll go again because service was good and I’m not going to SB these days but I’ll be sure to say less hot.

Great coffee and service!

Nice little place attached the Shell gas station. Coffee is a little overpriced, but find me a coffee shop that isn't.

My drink is always perfectly made by, an even remembered by, Jordan and crew at this location. Sure, I've been to other locations, but this is my favorite. I work nights and Mercury's espresso is a delicious form of rocket fuel. They have a really big drink menu with lots of options to please eveeyone. 10/10 recommend this location, specifically.

In my experience (Thursday-Sundays and some random other days always before noon) I have never received bad service or a bad drink. Who ever was working today about 11:45 is a great team. Fast, double checked my order, complimented my nails, offered the choco beans. I love who ever is the lead. She’s been there since I started going there and has always been great with recommendations.

This review is a shout out to the morning crew. Y’all rock.

Either change the closing time or have people at the location to serve coffee. Twice I ran after work to be at this shop before it closes at 7, but there is no one there at 6:30 or even 6:45, just OPEN sign is on. I hope management looks in to this!
