Dozo has great chicken gyoza dumplings, that got it off to a great start with me. They also have awesome ramen. Its very much on par with the better ramen in Phoenix like Hana. My go to is the tonkatsu ramen and they totally nail it. I wish they had actual bottles of sriracha though, because if you ask, they give you a little plate with some squeezed in there and being able to season it to make it more spicy would've made my day - they have a great miso based ramen too that I like as well. Their cha shu or pork is super tender and very flavorful.
They also have sushi rolls which are good but the main reason to check it out is the ramen. Stop by its a great date night location.
