As the 3 stars says, Frazer Diner is A-OK. It's what you picture in your head when you think of a Diner: amazing coffee, satisfying breakfast food in a big, metal hot dog-shaped building that looks like every item inside (including patrons) are from pre-1960. Portions were smaller than I'm used to for a diner, but the staff is friendly. Pro Tip: don't try this place with a party of more than 4 - it's a small place, and you will only irritate everyone.
It benefits from the Classic Diner being just down the street, which is a much nicer place (although NOT a prototypical diner), and is always packed. We tried for the Classic, and ended up (with about 10 other people who couldn't find a parking space either at the Classic) at the Frazer Diner, which is not necessarily a bad thing.
