The Lakeview is everything you could ever want in a diner: open 24h, cheap, cozy but roomy, great drink deals, and generally noms. It's the kind of place I would make "our place" if my friends and I were diner people.
The 24h brunch can be a godsend on a late night, sober or not-so-sober. The milkshakes are legit and delish (and probably 90% ice cream). The drinks are cheap and (can be) alcoholic. The servers are friendly and helpful. And they have bottomless coffee to boot. I'm a fan of the omelette, and they also do a mean root beer float - but so far, they've never gone wrong with anything I've tried.
The Lakeview is a staple. I may not be a diner person, but if I were, I would be a Lakeview person.
