Union Social Eatery is a lovely place with a very warm and cozy atmosphere.
The menu is pretty diverse. I think that most people would be able to find something that they like here. I ordered the Roasted Vegetable Flatbread and the Candy House Salad from the Gluten Sensitive menu. Both were delicious. Gluten free crust is usually kind of gluey and disappointing, but the flatbread was light and fluffy. The kitchen was able to accommodate my requests for light cheese on the flatbread and no walnuts on the salad with no problems. Everything tasted really fresh. The portion sizes were generous without being overwhelming. The menu is very resonably priced, especially considering that the food is obviously made with really good quality ingredients.
The big standout for me was the calibre of service. Our waitress was attentive without being intrusive. She was very friendly and knowledgeable, and seemed genuinely enthusiastic about the restaurant and the menu offerings. Our drinks were kept full, and our bill arrived promptly when requested. I have encountered a lot of pretty mediocre service in Toronto restaurants lately, and Union Social was a refreshing change.
I recommend making reservations. We went at 5:30 on a Wednesday night and it was quite busy.
