When it comes to airport food, it's usually a major disappointment. I usually avoid it at all costs, but was stuck at Pearson and needed some food.
I stumbled upon Hearth and sat down for a meal. I had an order of Hummus and some pasta with shrimp. The hummus was actually pretty good. Not the usual straight from the container airport hummus, but something that tasted like it was actually prepared from scratch. The shrimp and pasta wasn't very good, bland and oily.
The restaurant itself is a decent size with a nice layout. The service is also good as the food was out quickly and I ordered within a few minutes of sitting down.
Overall, this place isn't a destination to seek out, but if you must dine here, try the hummus.
