Catalyst Coffee Bar

The space is a little rough around the endges, but this is still a unique wonderful place with beautiful art and dynamite coffee. The staff were also friendly and inviting.

The perfect place for a meeting. Great coffee while surrounded by wonderful art. Plus, your purchase is supporting a non-profit!

From an employee of kaldis coffee I must say there is some good stuff they make there! Would for sure give a try if you love coffee!

I really enjoy this tiny coffee shop. Partners with Art St Louis so the back half is a gallery. Not recommended to bring kids in past the coffee shop which is fairly small. Lots of seating in the gallery area though.

There is no drip coffee after 12 I believe.

I love everything about this coffee shop!
It shares a space with an art gallery, Art Saint
Louis. Great coffee, has Pasteries, quiche,
and even bagel sandwiches! Friendly staff
and peaceful space. Definitely like ordering
A coffee and perhaps a nib or two and checking
Out the art and finding a spot to camp out
For awhile! Mississippi Mud Coffee Roasters
Cafe is a must try! You'll be sorry if you don't.

Fantastic smooth espresso. Great art gallery. Pour over coffee!

Had a small over priced mediocre hot cocoa 3.50+1 tip. Atmosphere is nice but a bit stark. Original gallery was nice.

I work downtown. Love to swing by after work. Never busy, hope it can stay in business. Great coffee flavors, not many coffee flavors. Walking distance to SLU Law, library, and the courts. Great place for a lawyer to get some work done before and after a hearing.

Best downtown coffee place! Great prices too.

Tasty cookies and super fine coffee
