Here, once again, I sit in CLE on a pleasant morning. Despite being a United Club member (and US Airways Club, err, Admirals Club member), I lack the motivation to schlep from concourse A to D, so I shelled $20 to sit in Airspace for an hour.
(1) I was the only person here (not including the 1 staff member) until one other person showed up. I'm not accustomed to a place so quiet.
(2) The coffee is very good. In fact, I'd daresay it's almost worth the price of entry compared to the swill served in the United Clubs.
(3) The price of entry is really $13, since you get a $7 credit for food, although nothing on the menu is $7! Most food options and $6.
(4) This place actually has plenty of power outlets at comfortable chairs with desks suitable for eating or working.
Well worth the price of entry.
