Mensho Tokyo is a ramen place I frequent regularly in SF and that has abolished tips. Every time I go, it's a pleasant surprise and I leave feeling happy about it. I can't recall right now if the prices on the menu are inclusive of the automatic service charge or not… but that's kind of the point. All I'm left with is a positive impression that this place is better than the norm. What I remember is at the end of the meal, I am told by staff that a tip isn't necessary, that it's already included in the service. Compare this to the way many people handle this: they include a mandatory service charge, or worse, a "healthy SF tax," all the while still happily soliciting further tips. It feels like a money-grab.
At the end of the day, it's all about execution, and unless you're able to fully commit to abolishing tips, don't bother trying.
The "healthy SF" 4% mandate is especially egregious. It's simply a common way for restaurants to falsely advertise prices. When I see it, I'm left with a strongly negative impression, and I tip significantly less as a result.
