Libertine Public House is a lounge atmosphere with some pretty good food.
I stopped by here with a friend for lunch and we started with the calamari. The calamari was pretty good and served in a pretty large portion (great for sharing). It surprised me how quickly the calamari arrived considering how busy it was. Following the appetizer, I had a gluten free flat bread pizza. The crust was very good considering it was gluten free, and the topics were all fresh and delicious. The flat bread was quite large, so it was definitely enough food (maybe even a little too much).
If you're looking for a place on Stephen Ave with a patio and some good food, you can't go wrong with the Libertine Public House.
