I've given this place two tries, and I think what makes me not like it is the overpowering rosemary-ish flavour of the gravy. I just don't like it. I'm sorry, but I don't. The last time it was also a bit congealed, which is not very appealing. Also...could do with more curds. And hotter gravy so that they actually melt.
I went out on a limb and tried the Nacho Grande version as well, which I thought would be the chili, guacamole, sour cream and salsa in place of gravy and curds, but it was in addition to gravy and curds. A bit much I think.
I always want to like this place, but there are just waaay better poutine places out there.
