Had Sunday breakfast at 9am. Place was only half-full at the time, mostly families and older couples. Service was very attentive - I got seated right by the front window and had coffee on the table almost right away. My waiter checked on me several times and refilled my coffee mug twice.
The breakfast menu has lots of variety. I ordered the Blue Plate Special: eggs, 3 meats, 3 slices of toast, baked beans, and a side poutine, with coffee included. I paid $18 for everything, tax and tip included. Not cheap, about the same price level as Denny's where I have been disappointed more often than not.
I have heard a lot of different opinions on the ESD poutine. I was born in Montreal, and I know good poutine when I taste it. ESD puts their own spin on it, and it's pretty good but nothing to write home about. The fries were crisp, matchstick, fresh & tasty - but not traditional Quebec-style fries. I saw on the show "You gotta eat here" that the gravy is based on steak sauce- I prefer a true gravy. But there was a ton of good quality cheese curds. So overall it was a nice change from boring hash browns. I think they must use steak sauce or A1 sauce in the baked beans as well; this did not work out so well.
By the time I left, the diner was about 75% full, but there were still plenty of good seats left. Peak time is after the nearby clubs close at 2am. An authentic diner experience overall.
