My husband and I will be visiting SF from San Diego and have made reservations at Boulevard. Upon glancing at their menu online, I noticed a disclaimer, "In response to the San Francisco Healthy Initiative, a 4% surcharge will be added. . ." Can someone please explain what the heck this initiative entails? I know this city is quite progressive, but I'd like to have some background knowledge before paying. Do only certain restaurants adhere to this? Cheers.
