This restaurant comes up as a gluten free options for Westminster, CO. I vaguely recall that the Denver location was excellent for a person with celiac disease - the menu was clearly marked, the servers were knowledgeable, and they even had tamari on hand.
I ordered from the Broomfield location tonight and will never do so again. The online ordering form offered the option to have my chirashi prepared gluten free, but it came with two ingredients that I know nearly always contain gluten: kani (fake crab) and seaweed salad. For those who don't know, the overwhelming majority of seafood salad for sale in the US is made in a single factory with conventional soy sauce (containing wheat) as an ingredient. There are a few places who may make it themselves, but I've lived in three different regions of the US and I've encountered one.
Unfortunately, my spouse and I made it all the way home before realizing these ingredients were present. I called the restaurant and confirmed that the kani is one of gluten free types, but the seaweed salad is not gluten free. The individual on the other end of the line did not seem to understand at first that if gluten-containing food is in contact with gluten free food then it is not safe for celiacs, which is almost as big a problem as the cooks themselves being unaware of which foods contain gluten.
In the restaurant's defense, they did substitute the miso soup I requested with salad (then left the salad dressing off) because of the gluten free request.
The dish was remade, but we did have to go all the way back to the restaurant for it. I would urge celiacs to avoid this place. My spouse enjoyed their meal and the remade one tasted fine, but it's clear that the staff isn't knowledgeable on the topic of celiac disease.
