Not a heck of a lot to say about this place. Fast Service, huge portions, open 24hrs, right in downtown Toronto. Has the ambiance of a bus terminal, but don't hold that against good 'ol Frans. Prices are all very reasonable.
Don't expect to loose any weight by eating here, but do expect to leave full and not too broke. In terms of 24h, all-day-breakfast, Diners, Frans is the benchmark.
