Nice discovery, good thing about Toronto, you are always finding 'new' places to eat.
This is a bit off College St, not necessarily a place you would normally be walking past.
I would give 5 stars; no debit/atm (had to go across street, up the stairs to a bar for atm; annoying in 2017, just get a debit machine, it's quicker/easier). The decor/interior is 'slightly' charming but mostly run-down/dumpy looking; needs new chairs, seating. Great spot for a reno, the patrons and staff would probably appreciate it.
Panzo is quick, ready and excellent; $6.75. Slices look good, they can get busy. Will definitely return.
