I went here with high expectations a few months ago, and I'm happy to say they were mostly surpassed. I am a former vegetarian with a healthy appreciation for vegan food, so I couldn't wait to try this place. My meal as a whole was fantastic The service was a little slow, but I think someone had called out that night, so that may not have been typical.
I tried the BUNN O))) as my appetizer. It was steamed buns/bao with enoki and other ingredients to fill it. This was the best part of the meal. As a matter of fact, it was probably the best dish I have tasted in over a year of living in Pittsburgh.
I also tried a Killing Yolk vegan deviled egg. I was surprised at how egglike the texture of it was. It was a very nice side.
My entree was called Headbangers Balls. It was tofu and lemongrass croquettes served with a slaw and rice. They were delicious.
My least favorite part of the meal was the dessert. I tried a matcha tiramisu called Terrormisu. The taste was enjoyable, as I am a fan of matcha, but the texture was almost jellylike and not like a tiramisu using actual dairy would be. I understand the difficulty of making these sorts of dishes vegan, but I have had dishes at other vegan places that managed to pull off a creamier texture without using dairy products.
Overall, Onion Maiden has a cool ambiance and fun theme. Although I had a bit of a wait to get my order taken and get my food, what I ate was worth that wait.
