Wabi House in Lower Greenville is hands down my favorite ramen place in Dallas. They have one vegetarian ramen dish and it is good.
The veggie ramen consists of noodles, enoki and shiitake mushrooms, snap peas, bok choy, corn, scallion, bamboo shoots and mayu oil. I always like the veggies that come with any ramen bowl but what really needs to be on point is the broth. I love their broth. It has a great earth-y flavor to it and is seasoned perfectly. I like to add an egg on top because I love the flavor of a nice, runny yolk mixed in with the broth.
