The rest of the review makes it clear that 'za stands for pizza here.

Lou Malnati’s Pizzeria
There are two kinds of Chicagoans. No, not North Siders and South Siders. We’re talking Giordano’s people and Lou Malnati’s people. Lou Malnati’s deep-dish is the pinnacle of cheesy Chicago-style goodness. Everything else on the menu–including pastas and salads–is passable, but not worth passing on the ’za. Get the butter crust. And don’t worry when you develop a Lou Malnati’s addiction: It will Fed-Ex pizza anywhere in the country.

Za (pizza)
"Za” is a clipped form of the word “pizza.” The term “za” has been cited in print since the 1960s, but achieved its greatest slang popularity in the 1980s.

So, in other words, it is saying that, although pastas and salads are also available, they are merely adequate and certainly not good enough to be preferred over the pizzas here, which are so good that you should not "pass" on them, i.e. you should not say no to them, not miss the chance to try them, etc.
