My dad loves to go down to the Ovaltine whenever he's in town as he used to go down there in the 1960's before the DTES became a haven for the homeless and drug addicted. The interior of the Ovaltine is kind of neat, it looks as though it probably did in the 1940's when it opened and the neon sign is one of the few remaining reminders of the heyday of old downtown Vancouver (a moment of silence for Save-On-Meats, please). Every time I've been there it's the same server, a middle aged woman who seems rather worn down from working the Ovaltine day after day. The food is average diner fair, burgers, breakfast all day, club sandwiches etc. I usually get the 3.50 breakfast special with a stack of pancakes. Decent food but nothing special. Breakfast is comparable to Bons or any of the other cheap greasy spoons.
The main drawback to the Ovaltine is the other patrons. Many of them have apparent mental health issues and there is the occasional argument between couples and you might have to endure some incoherent ramblings directed your way. I've never felt unsafe there but it could be a shock for those who have never left Kits or Yaletown. There is a police station behind the restaurant so cops often cut through the kitchen for a coffee. I guess this is worth checking out for snapshot of an old Vancouver diner, but it's also a sad reminder of what has been lost down there with the combined the social problems and historical buildings being torn down for new condos.
