Catalyst Coffee Bar

Best coffee in town, they make each perfect. It has a gallery inside, it was closed when we come, so make another reason to come back for that.

Amazing service from the gentleman at the counter, great coffee, and absolutely loved the art exhibition to view while waiting for coffee. Highly recommend!

Found this cute coffee shop surprisingly when I was walking around the St Louis downtown. It is like a cute art gallery with beautiful art work. I had the seasonal special, ‘ginger lemonade coffee’, which is surprisingly good! Come and check it out, not only the good coffee, but also the art work!

Stopped by for a morning coffee before hitting the road and found this was a pretty neat place. Only slightly marked down in atmosphere as I missed the gallery being open by a few days. The coffee was great and served quickly. Definitely recommend.

This was the BEST experience that I had during my 2 day stay in STL. My Barista was amazing and had very good camaraderie! Bob Marley serenaded the spot which set the tone for the atmosphere! My coffee’s tasted amazing! Tasted the love in every sip! Not to mention the vision and mission of this place for the arts was amazing! If I ever come back to STL. this place is on my list! Also have amazing art exhibits from locals!

Thanks for a good experience!✨

Good coffee for a good cause. Friendly, talkative barista, too. Probably the best coffee you’ll find downtown.

Had the seasonal “chocolate covered cherries” coffee and it was phenomenal!! The barista was super friendly and had some awesome stories to share. All the sales support Art Saint Louis, so happy I stumbled across it

One of the best coffees and best conversations I had during mi visit in St. Louis. Extremely recommended. The coffee is up to the level of a certified barista. I’ll be back. Thanks!

Coffee for a purpose. Catalyst located in downtown STL is serving up a delicious cup of coffee in a nonprofit art gallery. This coffee shop has a menu with a good variety of coffee and tea. Everything is made in house including there simple syrups. This is a great place to grab something caffeinated or maybe a pastry...or both, and check out some very cool artwork. There is a good amount of seating as well, so if you are looking for a laid back atmosphere to study or get some work done Catalyst is definitely a unique place to do so.

Wonderful vibe & the coffee is great! Definitely will be back!

This quaint coffee and tea shop is paired with a beautiful art gallery. Located across from an open park space, it’s a nice spot to grab a coffee. The two gentlemen working were kind and quick with service.

Great coffee shop serving thirdwave coffee downtown St. Louis! Connected to an art gallery and across from a park so plenty of good stuff to look at while you sip.

Friendly service with coffee roasted by two local roasters. Some places to sit in quiet art gallery atmosphere. Worth a visit!

Happen to visit St. Louis, and of course, did my research on the best coffee shops.. This spot didn't disappoint! The space is very artist and you're literally in an art gallery where they sell the coolest art and the coffee section is designated to support artists as a non-profit which is really cool.. very spacious and clean...

Believe I dealt with Todd. He was the coolest guy ever! Explained my drink and to my surprise, he made it perfectly! He even poured my steamed almond milk in front of me to ensure the exact pour. The Cortado was so rich yet not bitter...

20 yrs of drinking coffee and I honestly must say.. BEST COFFEE EVER compelling me to write a quick review...
If you're in town for a ball game or any type of business, this is the perfect spot! A couple blocks away from everything in St. Louis! Thanks Todd!

A lovely jem and a rare coffee place with lovely people and world class coffee!

So cute inside. I got a carmel and coconut latte and it tasted EXACTLY like a samoa. I think it is seasonal but I bet you could ask someone to make it if youre really nice because the barista was so sweet there.

Enjoyed being able to sip our coffee while checking out the art exhibits! Definitely a cool experience.

Give been chauffeuring a group around town the last 3 days. We were in the area and asked about a coffee shop. I knew about this place and the reviews were great. CCB won't disappoint. Coffee was awesome and at a incredible price. While you are there take a moment to enjoy the artwork of our talented local artists.

Good espresso (barista pulling real shots), and friendly service and attached to a local art gallery.

This a great coffee spot in downtown St.Louis. I had a delicious latte with oat milk and an awesome cranberry pop tart. The coffee shop is located in an art gallery which is an added bonus. Friendly people and great service. Definitely make sure to seek out this gem!
