If the prices on the menu are just 10% higher, this is fine. You know what you're getting in to and can always decide to order something cheaper or not eat there. If the prices on the menu are the same, but there's a note at the bottom of the menu saying "additional 10% fee to support our workers' healthcare" (or something similar) they are technically telling you, but this is certainly misleading (possible to miss the note, and it's harder to do math) and is very annoying. I've noticed several restaurants doing this. The new CA law explicitly bans this practice. If the prices are the same and you aren't notified until you get the bill, this is highly unethical and IMO fraud. There's a restaurant near me that does this; they offer to remove the fee if you notice and complain, but also try to guilt you into paying. The new CA law bans this too.
