It depends upon how you define "success." I visit California regularly, and since the new minimum wage law went into effect, I've noticed reduced hours, reduced staff, and increased prices. So now my normal breakfast spot isn't open when I want to go there, so I eat at home. The places I visit when they are open are mostly empty, because the customers don't want to wait longer and/or pay higher prices.
So aside from the fewer employees getting a raise, the businesses are now under financial stress because of the reduced revenue, the customers have fewer options for where to eat, and the State of California and the local city/county governments will receive less tax revenue from these restaurants.
Like most of the other recent California legislation, it's a "success" at further damaging the local economy and encouraging people like myself to stay away.
