Had an in-person meeting scheduled at Kaldi's; arrived early not knowing what to expect. Fortunately, I found the place to be spacious, the service friendly, and the coffee great and well-priced. The Wi-Fi is fast and there are many open spaces to work from, including counter tops at the bar. It can be a bit noisy, but I managed to get two video calls done with no major issues. Highly recommend for anyone passing through Silver Spring/Washington, D.C.
