My friend and I went to Dirty Dogs for Montreal Mac & Cheese Week but, as mentioned below, there weren't really any Mac & Cheese "specials" per se--just regular menu items. Regardless, we still walked away having sampled their M&C and very satisfied.
We ordered the Notorious P.I.G. and the Maurice Richard dogs and the Mac & Cheese Poutine to split--cause go big or go home right? The dogs were superrrr tasty and the foie gras on the Maurice Richard was on point! The Poutine M&C was RICH--mac and cheese PLUS cheese curds is a whole lot of cheese and I loved every second of it. Wouldn't recommend if you're not into that sort of thing. Nothing particularly oustanding about the mac & cheese in itself I wouldn't say but the dish as a whole was a bowl of yumminess.
Not too much seating area in Dirty Dogs and it's quite smokey--would be great to do takeaway and head to a nearby park in the summer.
