Came here to Cartel Coffee Lab in C section of terminal 4 at the airport. Quite frankly, we didn't want to walk all the way out to the Starbucks that was in the area after the TSA check so it was nice to stumble upon this gem.
I got a small iced mocha and it was pretty good. It was definitely better than what Starbucks has to offer. My drink did take a while to make but I'll chalk it up to the baristas carefully crafting my beverage. My flight was delayed by 20 minutes so I wasn't going anywhere anyway. My friend got the spicy coffee (I forget the name) and it was quite unique. I've always wanted to try something like that but couldn't commit to a full drink. It was definitely spicy. I'm sure it's an acquired taste and lots of people like it, but I probably wouldn't want to be as adventurous next time.
I'll have to try some of their different offerings next time I'm there.
