Costco?

We went to a baby shower yesterday. It was a very non-traditional affair, more of an afternoon get-together with a pregnant woman! For lunch they served up some sandwiches in those great ciabatta rolls from Costco.
In principal it would seem that I am fairly anti- Costco- a lot of nasty, low quality overpriced food exists between its massive walls after all. But increasingly we are starting to think about joining. In the non-food realm there are some great deals on tires, electrical items, and bedding. Not to mention the really awesome return policy.
Foodwise I am generally not a fan, but there are a few items of note that I really do like:
In addition to the ciabatta rolls there is: cheese- fresh mozzarella did buffalo (to die for) and some wonderful brie. Vegetables: great hot house tomatoes and English cucumbers (some of the fruit is okay, we don't go through fruit in Costco sized portions, whereas we can easily go through 2 packs of tomatoes a week). My fave item in the veggie section is the peeled garlic- a laziness I never thought I would go for, but after having one container at such a low price I am converted! In the frozen section there is the really great spinach ravioli and a couple other occasional items. Then I like the big bags of pinenuts and other random ingredients that store well, so that a huge quantity is not a problem.

We still haven't totally decided, but with the taste of ciabatta still on my tongue I am leaning towards membership.
