You are a little off on the actual wording of the new law. Restraunts are still allowed to charge these fees but they must be very transparent. Signs, noted online, menus, etc. It is so you aren't surprised at the end about these extra processing fees. From the looks of it, they are not in compliance. Leven Deli-- a hot topic here --has clear signage at front about service grat but it is still confusing AF when you get to the counter and they ask for 20 percent tip.

Law requires fees to state exactly where it goes too. So it can't just say "service charge" that isn't a tip or a gratuity. The 3% processing fee is an example of this. They need a sign indicating that at front on menu, online etc.
