Fortunately, when we talked with our server, she informed us that they have an off-menu vegan roll and we promptly ordered several of them—Japanese pickled radish was the primary ingredient, at least on that day. Also, they specialize in Japanese grilling and so there were several options that were of the sides-type portions. We devoured the roasted corn and enjoyed Shishito (Japanese sweet peppers), Shiitake mushrooms, Brussels sprouts and baby bell peppers.
Clearly, Kengo is a place that caters to fish and meat lovers, but the good news is that you can get a filling vegan meal. Kengo is extremely charming; we felt like we were in NYC with the cramped space (only 23 seats), the highly-curated beer and drink menu and how the friendly staff called out greetings when you enter and when they only had one left of a particular item.
With the small space, we did end up waiting with drinks along the back hall—it was a Saturday night—but it moved pretty fast and they even brought complimentary edamame over to those of us who were waiting. A nice courtesy.
We had a great time here! Not a lot of choices for vegans, but well worth a visit, especially with your foodie friends!
