I'm going with a review in between the nay sayers and yay sayers for now. I really like the idea behind this new place and will continue to try it over the next few months to see how they iron out the kinks.
The space they have on Dundas West is awkwardly laid out and not very inviting for a dine-in experience. But the mac 'n' cheese... Well, I really liked mine. I had the egg-celent: double smoked bacon, roasted bell peppers, leeks, fontina cheese and a freaking deep fried poached egg on top. Sinful. Cheesy. Egg yolk explosion on your mac. Yum.
Another friend had the plain mac 'n' cheese and finished it in 2 minutes, which is always a good sign.
When you go, make sure to have the fried cheese coins: tiny cheese bits breaded and fried that you can dip into their selection of homemade ketchup.
