    Last time we went, it was great. This time, pretty bad. Service was awful; no one even brought water or acknowledged us for a very long time. We brought out of town family with us and were embarrassed! Soup was awful; it tasted like hot water. When I told the waitress, she seemed aware of the problem, but didn't fix it. Our lychee drinks and salad were bad. My mushroom appetizer and entree were pretty good. I don't know what went wrong. We probably won't return.

    We hadn't been to Sushi Zanmai in awhile and decided to go back before a show at the Boulder Theater, I was pleasantly surprised with how excellent the sashimi was as well as the service. It wasn't super busy and that helped the ambiance. Glad to have Zanmai back in regular rotation!

    The food was delicious! It was unusually loud for a Japanese restaurant but that was due to a few patrons.

    Extraordinary service - freshest sashimi platter and sushi platter - all exceptionally great. We loved the tatimi room - so quiet on a super busy graduation weekend. The six of us were able to converse delightfully! Truly a memorable evening. Thank you!

    Sushi Zanmai graciously made room for my party of 10. I've eaten sushi at several restaurants, and this was one of the top dining experiences!

    Horrible behavior from hostess at graduation dinner. Approached us to say “we need your table for the next reservation “. Hadn’t received a bill, hadn’t seen server in a while because she was totally overextended (not her fault). Spent over $500 and hostess was rude in shocking direct approach to table—will not go back.

    It was just an average experience and food and drinks were poor. We have had sushi much better at other places! Server was good!
