We've had a couple of restaurants in NYC go tip free, instead building the cost of service into the base cost of menu items. Unfortunately it appears that this can be a challenge because consumers aren't used to the higher cost menu items. Even though a $30 entre with no tip is roughly the same cost as a $25 entre where a tip is expected apparently consumer behavior changed significantly. Quite a few places have abandoned their gratuity free plans after a couple of months of testing.
There might be a bit of a prisoners dilemma problem here. If every restaurant eliminated tipping consumers would soon get used to new prices, but when only a few do they stick out as feeling more expensive (even if they really aren't).
We might currently live in a stable but non-optimal equilibria.
I bet this is due to the same effect that leads to .99 pricing. People concentrate the most on the first digit of a dollar amount. So if all your first digits go one number up, the consumer is going to feel the mental pinch and consume less.
One solution would be to restructure no-tip pricing in a way that causes the minimum number of first-digit changes (i.e go ahead and make that $12 entree $17, but make the $25 one only $27).

They have lobbied hard to keep FOH staff wages down (up to 3x less than ROH) supplemented by tipping.
The driving force for this is that your wage bill is not as strongly correlated with demand - no customers means no tips so your FOH staff pay the price for your poor management.
I don't think this is an industry conspiracy so much as a particularly challenging market. The consumer is a vicious seeker of value. This depresses wages and also makes it so that restaurants aren't particularly profitable enterprises(1).
