Zen Gardens has amazing food and beautiful decor. All of the menu items are vegetarian and most of them are vegan (the non-vegan items are clearly labeled). I visited Zen Gardens while on a trip to Waterloo with some friends and all of us agreed that Zen Gardens was the best restaurant that we ate at during our entire trip (which was especially impressive, since most of my friends were not vegetarian).
I started out my meal with a "firewater" smoothie (cranberry juice, coconut milk, cinnamon and vanilla), which was indescribably good. Next, I had the assorted seitan appetizer, which consisted of a generous portion of bite-sized chunks of about 5 different flavors/textures of seitan. For my entree, I had the ginger "chicken," which was a sliced chicken "breast" covered in a delicious sauce and served with an incredible seitan-topped salad. The food was so good and the portions were so generous that I didn't even have room for dessert.
