Upon the tradition of purchasing coffee in Seattle (other than Starbucks) we arrived here on recommendation from a native and we were very pleased. The cosmic theme really elevates the experience and the tastes are out of this galactic corner. I ordered the Mars, a spicy mocha. My Colombian friends were really impressed.

Great coffee shop with a nerdy vibe. They offer plenty of board games to play, and ample seating. I ordered the Mars which had a touch of spice and it was very tasty!

This cafe was out of this world! Not just another coffee shop, cafe cosmos has a host of unique, themed menu items, late hours with beer/wine, and a huge community game area. The coffee was exceptional and the service spectacular and helpful. We found a new favorite place in Seattle!

Great quality coffee from Fidalgo roasters, excellent baked goods selection, cool vibes/ambiance and friendly staff. Love the board game setup. Definitely a great spot to grab a bite, coffee, or hang out with friends.

Great ambience and service :) Love their interiors and art decor, goes perfectly with their name! The specialty drinks menu is unique and they have a collection of board games for dine in

Fantastic coffee shop with awesome coffee and great staff. Great recommendation for drinks from them and it’s a cool place to hang out. I really liked the vibe of this place. Wonderful place! Be aware they don’t give you lids. I was a bit puzzled about this-but I think it’s because of the plastic? Quite interesting walking away without a lid though.

We don't have a lot of themed cafes in Seattle so I was very excited to check this one out. I got the "io" which is a butterscotch latte with brown sugar, whipped cream and caramel drizzle. It was 7.72 after tax for 20 oz. Not sure why prices were erased from the menu board. The latte tasted really good. Looking forward to try their other drinks! They have lots of board games, books, and an interesting decor.

The coffee is actually great. Also service is lovely and the restroom is spacious and clean. I like that they have books I'd like to read, and that they really take the cosmos theme seriously.
