Claim: Some sushi places charge extra for brown rice.
Verdict: Unverified (45% confidence)
Explanation: We were unable to find credible sources that support the core elements of this claim. None of the retrieved sources directly address whether sushi places charge extra for brown rice. The search results primarily discuss other aspects of sushi dining, such as charges for uneaten food or general restaurant reviews, but do not confirm the specific practice of charging extra for brown rice. Therefore, the claim remains unverified due to the absence of direct evidence.
