This one is nested right across from C-21 (for review). Clean, has everything stocked (sandwiches, drinks, etc.) but then again I visited it prior to 8 in the morning.
This particular one is heavily trafficked by C-gate incoming and outgoing travellers so I assume it sells out pretty well.
General airport pricing so it shouldn't be any surprise at the higher costs. The guy manning the cash register was super friendly which is appreciated when you're already grumpy from having to get up super early to travel.
