I have been coming to this roughly once a week for the last 6 years, all the way down from the McIntyre Building at McGill. Note that I have always done take out.
This is an incredible cheap and amazing place to go for lunch, with freshly prepared sandwiches. I almost always get Jambon de Bayonne + Oka cheese and end up with a bill of just over $5.40 after the tax! In addition to that, around 15 different kind of sandwiches are offered.
Salads (probably around 10 kinds including fruit salads), spring rolls, and quiches are also available. I have tried the potato salad and was also amazing. However, you will be full with just a small sandwich!
