Hillside has been a favorite pizza place for several years, and the quality has been consistent. The restaurant uses many local and organic ingredients, and the quality is apparent. In addition to pizza, the salads are excellent, and there are sometimes vegan baked goods for dessert. In one of the locations seitan and tempeh sandwiches are available- call ahead to either the Deerfield or Hadley restaurants to find out ahead if you have your heart set on a sandwich. The portions for all items are ample.
The only slightly negative experience I have ever had at Hillside was a couple years ago when I found out that ordering just a slice with vegan cheese meant that staff scraped off the dairy cheese from a slice and then rebaked the slice with vegan cheese. I talked with staff about my dislike for that practice as a vegan who would not want to eat food that had at one time contained dairy, and I do not know if this practice continues. However, if you order a whole pie with vegan cheese there is no cross contamination.
Cons: Slices may have first contained dairy , Not open every day
