Review of Osha Thai Kitchen and Sushi

I would not trust - from the mouth of the owner via messaging:

Thank you for the message. The sashimi sampler GF indication is a mistake on the menu. There are many ingredients in sushi that contain gluten. If you have a gluten allergy, you will need to let your server know when ordering so they can communicate directly with the sushi chefs. Please note that given the number of items at the sushi bar containing gluten, we are not able to guarantee against cross contamination.
