I picked up a Combination Pizza, sometimes called a "supreme' at other pizzerias, which is topped with a fairly standard mix of pepperoni, bell peppers, onions, olives, sausage, and mushrooms.
The wait at my super busy Costco is always pretty long. It actually took me over a half an hour to get my pizza and some people had been waiting over 45 minutes. Even the people who had called and ordered ahead ended up waiting. My local Costco is a zoo on the weekends especially.
So the good... Lots of fresh veggies. Plenty of cheese. The sauce is balanced and slightly herby. The pepperoni and sausage carry a good flavor and the sausage comes in good-sized chunks.
The not so good... the crust is a bit gummy and soft. The end crust is satisfyingly thick, but there's not a trace of crispness to be found. Fortunately, Costco Pizza warms up really nicely in the toaster oven which adds a thin, crispy layer to the crust and tastes much better. Yeah, Costco' toasted cold pizza is better than Costco's fresh hot pizza. Go figure.
Overall, Costco's Combination Pizza is probably the best pizza bang for your buck in most neighborhoods and is pretty good, but hindered by a lack of crispiness.
