Woo hoo! The Counter has the vegan Impossible Burger! It's thick and designed to be "like meat" - with the marketing spin that "it bleeds." I had mine well done, so no blood for me. It may be a bit too intense for those that cringe at the idea of meat, but it was pretty good. The Counter is also sensitive to cross contamination and cook it in a separate grill.
You need to inquire about what bread and toppings are vegan, but the servers can bring out a list. They don't have any vegan cheeses.
We got ours with sides of shoestring and sweet potato fries - both are great so it was hard to choose.
They have a veggie club and salads that can be made vegan too. I've heard the non-vegan burgers are good too but can't personally confirm.
Service was fast,friendly and accurate. If you sit by the window you get to see (and feel) light rail trains go by. They also have a nice patio out back for when the weather is agreeable.
