In truth MY experience was a 2 - but I'll give the Dinerbar an aspirational 4 now that I know what to order on my next visit. On the positive side the place has great service and atmosphere and decor so sharp you could cut yourself. But...
My principal complaint which the Dinerbar could and should fix is that they have a large menu of mixed drinks...NONE of which cater to those men and whisky babes who like their drinks savory, spicy, and/or bitter. It is truly sad when the least sweet thing on the drink menu is the Margarita. And it wasn't as if there was a massive selection of stouts or porters or IPAs to lead me elsewhere.
And since I was stuck with a Margarita and it was Cinco de Monday (so the tacos were 2 for $5) and the bartender recommended them I went for 2...and then 4. And they were passable...but not actually good in any real sense. Certainly no where near as good as the burgers, poutine, and other dishes I saw being feasted on to my left and right. So I ended up more than full with a drink for $20 after tax and tip - which must be a record for the Dinerbar. But I would never order that way again.
