Catalyst Coffee - Mar del plata

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!

These people were so nice! Even though they were busy they talked to each customer and made coffee quickly. Their seasonal coffee was good and so was the drip coffee. It was cool to look at art while we waited. Oh and the homemade pop tart pastry was delicious!

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

Down home atmosphere and very relaxing. Good worker and he's very nice to guests. Very càring. And super fast at making drinks

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.
