I'm a vegetarian, so I always like to scope out a city's vegetarian restaurants when I first arrive. The Coup seems to be Calgary's best-known vegetarian place, so it was high on my list of Must Eats! Unfortunately, I found both of my meals there to be real letdowns.
Both times I've eaten at The Coup I've had Mexican-inspired dishes: once a "taco" and another time "huevos rancheros". I use quotations marks as the terms really must be used loosely- both dishes were extreme distant cousins of their namesakes. I found the taco to be overly heavy on crunchy chard stems, and strongly lacking seasoning. I found the huevos rancheros to be dull and uninteresting, with an overly earthy flavor from the sprouted-grain tortilla. Both dishes lacked seasoning, where all it would have taken was some fresh cilantro and a splash of lime juice to make the dishes passable. Without that fresh flavour, both dishes were nearly bad enough to warrant being sent back.
I just checked The Coup's website and it doesn't look like much (if anything) has changed since my first visit there a few years ago (my second visit was in the past year). I definitely will not be returning until I see evidence of innovation on the menu. There are way too many other restaurants with great vegetarian options in town.
