The machine at YC CL and BC CL is definitely Nescafe, but there is a separate pot that is out in the reception area starting at 6:30am (honestly not sure if it stays out there all morning, or if they move it into the lounge once it opens at 7am). I am pretty sure that is something other than Nescafe, but I never tried it. I treat myself to lattes on vacation, and the machine stuff is fine with me. There is also a variety of flavored syrups to add to the coffee, if you want.
HTH!
ETA: Here is a pic of the machine from YC CL. It is the same at the BC
