I know. I know. Whole Foods is a grocery store. However, I just discovered a couple days ago that they have a "restaurant" inside the Cambie branch.
Essentially, you can either ask the friendly employees of Whole Foods to get you food from the fridge case (not sure what it's called), or you can use the containers/plate in the buffet like station.
They have many choices from a variety of soup and salad, entrees and side dishes, and more. They also have a whole keto section.
How much does it cost? $2.95 per gram. I had way too much fun getting food, and I'm kinda hoping to get some more. I tried mostly vegetarian dishes and food from the keto section. If you are craving keto food in Vancouver, drop by Whole Foods grocery food area/restaurant.
