In my 15+ years experience, I've found 1-on-1 conversations at a shared table (sometimes even at a coffeeshop over coffee) to be provide just as actionable and informative feedback as those of a lab environment. Add in the dramatically lower price tag and the honesty of a human-to-human conversation and I head to the coffeeshop everytime. I do believe there are one or two scenarios where the lab is preferred. I try to steer away from those projects.
