I don't shop at Whole Foods that often since it isn't that close to me. There's a Shop n Save a block from my house, so I buy most of my food there.
One thing about Whole Foods is they specialize in fresh fruits and vegetables. Their produce is definitely impressive. All of the oranges, lettuce, berries and bananas peppers are perfectly ripe. They never have spoiled or bad fruit.
The pastry section is definitely worth checking out. They have fruit tarts and a lot of different flavored cheesecakes and cannolis.
Whole Foods seems more expensive than Aldi but less expensive than Giant Eagle.
