Went to the new one in Markham (Leslie and Highway 7).
230 Commerce Valley Dr East
Tried their 8 oz Hero Burger (comes with sliced onion, tomato; also asked for honey mustard). Got the combo which included fries and a soft drink.
I thought the burger was quite good. The meat was grilled just right but I wish it was a little thinner to make eating the thing a little easier. Mixed into the meat was a certain something...malt vinegar maybe? Next time gotta ask the chef at the back who I can only see from the neck up. He better have pants on. The bun was so fresh (not a segway). On top are poppy and sesame seeds. The fries had some skin on them (ala NY Fries)...but I wish they were a little more crispy.
They need more in the way of drinks...shakes, maybe? And it would be cool if they had a toppings bar instead of ordering it off the menu. That way I could use their sauces to dip my fries like the Euros do.
The decor is kinda trendy. I thought I was in an oxygen bar for a second. This particular location is in tandem with Lettieri Espresso Bar (like a Second Cup/Starbucks).
In summary: Yummy, would return.
