Angel's Diner is now called "Fifties Diner", but has not really changed much. Although I work literally across the street, I rarely visit.
The menu offers a variety of the regular greasy items you would expect from a diner, nothing out of the ordinary. I've tried their breakfast, a BLT and their fish & chips and they were all decent, but nothing to rave about. The portions were a good size - I have never left hungry.
The prices were mid-range, not a steal, but also affordable.
Interesting: I've spotted Elvis Stojko here a couple of times.
