I tried Zen for the first time yesterday and was pleasantly surprised with all the vegan options! They have a separate 'green' menu with asterisks for vegan items. I had the tofu lettuce wraps and the veggie roll. The wraps were fantastic. The tofu was lightly fried and mixed with sauteed onions and peppers - it was relatively spicy, but the lettuce balanced that out. This could have easily been a meal for one person instead of an appetizer. The veggie roll was ok - nothing special - avocado, carrot, asparagus, if I remember correctly. They did have quite a few other options (i.e., shiitake, avocado, beet, etc), so I would certainly be willing to go back and try other rolls. Overall, a win for the Bishop Arts District and Dallas vegans.
