They sell all my favourite Italian products - my San Marzano tomatoes, my chemical free beans, and Illy Espresso Pods! The trek out is always a pain, but if you make a morning or afternoon out of it, it can be quite lovely. They have delicious lunch service as well for great prices. You can get a sausage or veal on a bun with lots of meat, sauce, and veggies. They also have great prices on their fresh pizzas. My favourite though? An Italian donut and their nutella cappuccino. I think about it constantly.
They make a great fresh pizza dough as well that I frequently buy - makes for a yummy pizza. Their cheese is also much cheaper than anywhere else I've been, as well as their gnocchi.
They are my benchmark for Italian canned goods and other products, I can't go anywhere else now.
