I've been to this location both as a meat eater and as a vegetarian. I've had their regular burgers, beef and chicken, and they were both fantastic. Fries? Superlative.
Since becoming a vegetarian, veggie burgers are high on my list. Unfortunately GBC's veggie burger is bland, boring and forgettable. I actually felt kind of sick after eating it. It tasted like rubber bands. Furthermore, they don't have a vegetarian gravy, so I'm unable to enjoy a poutine.
For a company touting they are a "gourmet burger company," it strikes me as odd that their vegetarian offerings are horrible. One would believe they would be excellent in all burger offerings.
