So, I came here back during their opening week and fully expected them to be working some of the kinks out of their service/food. I had dinner on a Friday night with four others.
We arrived around 6:30 and had no problem getting a table immediately. I somehow doubt that this would be the case now, given that they've been open for a little while, so I'd give yourself a little time to get a table. Once seated things got off nicely.
Some of the points in the more critical reviews were observed by my group as well, especially in terms of the servers not quite knowing how to be attentive to tables properly. If this weren't a brand new place, I might have given them 3 stars instead of 4, but given the level of attention from the owners and manager, I think they'll work some of these flaws out in the coming months.
I will say, everyone in my group really enjoyed their meals. Also, the wine and beer on tap were great and a big hit at our table.
Toronto is in dire need of a place that does meat and vegetarian dishes equally well, and I'd say that Harvest Kitchen fits the bill nicely. We will be back again.
