McDonald's is also testing breakfast pastries in San Diego.
McDonald's executives have conceded that they rolled out too many new items too quickly in the past year. That led to kitchen operations becoming too complicated and orders taking too long to fill.
So the chain says it will slow its pace of new offerings. It's also trying to add variety using items already on its menu. That might mean introducing McWraps and Quarter Pounders with different toppings and sauces, rather than new burgers entirely.
