Great eating option for those on a budget. I have been here several times and I'm pleasantly surprised with the size of the dish every time. It's not gourmet food - but for 5$ you should not expect it to be! Drinks are priced like every other bar around. During lunch (weekend) and dinner there is always a line. They have a take our option - but it costs more (?!), and the one time we tried it - it took more than half an hour to get the food - and we could have gotten a table by then anyway.
The Quebec version - Le bureau de post - has the exact same menu - with different design but similar ambiance.
I can recommend everything that I have tried so far (except the poutine - it's not very good, but there is plenty of selection otherwise).
Good for both vegetarians and carnivores.
