I'm in Cornelius from out of state, and I've enjoyed sitting at this coffee shop and working on my computer in the afternoons! It has a great environment and is quiet enough for me to get my work done.
The coffee is excellent, too. I've had the iced coffee, which is good, but my favorite is the latte. They have a huge selection of tea. They have great cheesecake and macarons, too. Plus, their macaroons are under $1, which is the cheapest I've seen them anywhere.
I've read reviews that say Waterbean is expensive, but I don't think it's any more expensive than any other coffee shop I've been to! The staff is very friendly. This is just a great place to hang out!
