I was just there today (8/8/18) and they were open. I think they open around 1:00PM
George is not the best about getting to the phone since he prioritizes people in the store over phone calls. But yes the control lab is open usually at noon til about 7 or 8 on every day of the week except Monday. Occasionally they open late due to life circumstances and such. But if you call after 1pm you will have the best luck of reaching the shop (showing up in person after 1pm is also a sure fire way to reach George).
