Washington State is home to forests, mountains, rivers, lakes, volcanoes, beaches and bays. So, it's not surprising that a state with such natural beauty works hard to find a balance between safeguarding the environment, protecting consumers and maintaining a thriving business community. Like most western states, Washington has a fair amount of state and city level licenses. However, it maintains fewer than neighboring Oregon or giant California below that.
In Washington, pizzerias are restaurants also. That includes sit down Pizzeria's and take out/delivery establishments.
