I go to Coco quite often on my way into work. There is often a line of a few people but it moves pretty quickly. The decor is very modern and interesting. There's an upstairs lounge and they even serve beer in the cold case if you want to grab a drink in the afternoon.
I usually just get a drip coffee so I can't speak to their espresso drinks. The coffee is pretty good though not gourmet. I prefer it over Starbucks and many other chains in the area. Their breakfast sandwiches are quite good. The one healthier option - the chicken sausage and egg bagel - is kind of hard to eat though. The sausage casing causes the links to pull completely out of the sandwich on the first bite. Kind of silly to point out but I don't get this one anymore because it won't stay together.
I've gotten a chicken Cesar salad before and it was decent, though not worth the price. For a coffee, yogurt, and salad I think my total came to $21.
I like the place but it's not my favorite. Definitely a convenient and decent choice around Trade and Tryon though.
