"Omen is absolutely awesome! The people, atmosphere, space, and coffee all live up to the hype. Every time I mention Omen, I hear others share their own great experiences there. What really makes Omen stand out are the community events—Bible studies, worship nights, and so much more—that create such a welcoming and uplifting environment. Highly recommend!"

"A fantastic experience. I visited Omen Coffee while waiting for my Amtrak back to Chicago. I googled plenty of shops but this one seemed the best to sit down and spend time. And I was absolutely right. The cafe is spacious with comfortable seating, and the barista behind the coffee bar was absolutely helpful, kind, and friendly. If I were a STL local, I'd be here more often. Cheers ☕"

"I have been several times now so my review is a accumulation of all the visits. First and foremost the coffee is... OK. It's been inconsistent in the quality of the cappuccinos I gotten (too bitter/burnt, milk tasted off) and the lattes have always been too milky. This most recent latte I got left a weird tingle on my tongue and soured my stomach. Staff has always been friendly and knowledgeable for the most part. Atmosphere is... Interesting. There have been times where it is packed and it feels like an on-campus coffee shop with everyone working on something and lots of buzz in the air. Then the times I've come and there hasn't been many people, but the music was still turned up as if the place was packed, loud enough that I didn't feel like sitting inside. Also, I have been made aware of two things, 1) This place also operates as a church. I'm sure that appeals to many but I find it off-putting that a (presumably) for-profit business also holds a church service, and also sells Christian-related "merch" (again presumably for a profit). 2) The owner of the business has made questionable public posts regarding the LGBTQA+ community. Overall, the coffee is what I come to a coffeeshop for and this one has consistently disappointed me."

"Cute shop, spent my time studying here. I only got to try the matcha so would try their coffee next time! I enjoyed the matcha although it was on the lighter side. Staff was nice and drinks came out fairly quickly."

"This is a fantastic coffee shop that truly deserves all the praise. From the moment I walked in, I felt incredibly welcome—the staff is so friendly and genuinely attentive. The atmosphere is awesome, creating the perfect cozy and inviting space to relax or work. And most importantly, the coffee is absolutely perfect! Every detail here is good, and I thoroughly enjoyed my visit. It’s clear they care deeply about quality and customer experience. I'll definitely be back!"
