Hmm. I'm on the 3-4 line here. It's not that Umami Buns is doing anything wrong, and I liked the spicy tofu buns (think short, fat tacos with Asian fillings) with edamame, but if you aren't eating meat, you definitely need to upgrade to the pricier ($10 vs. $7) three-bun combo lest you be hungry again about 90 minutes later. I could probably have eaten five of them without too much difficulty. But the buns are fresh and inventive, you can fire them up with some sriracha, and Umami Buns was one of the tastier and better choices that I made during a snakebitten foray into vegetarianism in the cow capital of the U.S. Since I'd do it again despite the reservations, I'll round up. As the menu is only three or four items for this truck, check out the photos and you should get a comprehensive idea of whether this looks like your thing.
