The fast, friendly drive-thru service at Madhouse put them on the map for me. I had my little dog and they even gave him a treat at the window! (I've even heard they're dog-friendly at the patio area.) I ordered the Nutella white chocolate mocha and my roomie ordered the red velvet mocha. The Nutella drink was a bit watery for me upon the first sip, but when I got to the good stuff, it was indulging enough--although if I didn't know it was Nutella, I might not have guessed so. My roomie said something along the same lines about his red velvet drink. He couldn't exactly distinguish the red velvet flavor, but agreed he had an enjoyable drink. Overall good experience, and I would definitely like to sit down inside that artsy area with a book someday!
