I am not an expert and I've not been to that particular PC, but, in my experience no domestic PC serves what can reasonably be described as a "nice breakfast."
A bagel (maybe,) good selection of fruit (usually,) and of course coffee-- sometimes espresso, cereal, juices, etc. But in my limited experience, never a cooked breakfast.
Undoubtedly someone knows that PC better and will correct, but in general the PC is a nice place to kill some time-- but I'd never intentionally "build-in" a visit to one on a trip.
Oh, and yes, I'm sure it's open at that time.
