Harvest is a great store for both health food basics and special treats. It is a nice, small alternative to bigger, more corporate health food stores.
They feature a great produce section, nice little deli, fresh cheeses, and a decent beer and wine selection. They also have staple food (pasta, cereal, etc.) and a nice health and beauty section.
The store is very clean, and the staff is usually quite nice and helpful. It's a great little store.
