What is perhaps the best coffee house in Dallas is on Routh Street in the State Thomas neighborhood. It's not a main thoroughfare, if fact it's kind of hidden around a corner in a neighborhood of single-family houses from the late 19th Century. It's set up like a house inside too with tables, sofas, books and even a piano. The off-the-beaten-path location doesn't keep customers away, it seemed busy throughout the day Monday. I know because after stopping by in the morning, I returned to fetch my hat in the afternoon. It was still there, sitting on the floor unnoticed by students typing away on their laptops, taking advantage of the wi-fi. Crooked Tree Coffee.
