I am regular at Hi Sushi, in fact I don't even need to order any longer, they see me and ask I will 'Have the usual?'.
My usual is the Tofu Don, it comes with a free miso and for under $10 bucks it's a charm. So delicious and filling. On the vegan front they have eggplant miso, a vegie bento that's vegan if you ask them not to dress the salad. They also have miso, edamame, and fried rice (ask for no egg). So the options are many ( iahven't listed them all. The food is consistently delicious and the service kind.
Also, just a tip, the sushi isn't vegan (even the veg one) as I have seen them use the mayo to on their gloves liberally to prevent rice sticking when they make the handrolls. read more
