A coffeehouse with a line is usually a great sign. I say "usually" because there exist some cafes that will make questionably poor choices that cause customer waits, like a lone barista operation pouring exclusively pourover during the morning rush or the cue being held up by someone who ordered 15 creme brûlée lattes for the office. But when a hefty line forms despite four employees moving like a Swiss clock, I take solace in the fact that the wait is almost definitely worth it.
