I would come to this market every week if I lived in the area! There's a lot of floral/garden shops outside and the inside is filled with fresh produce and foods.
It's not difficult to find since there's a large "Atwater" sign on the building and you can spot it by looking at the hordes of people heading/leaving there.
The inside is pretty organized and it's easy to walk up and down the rows of vendors inside. Some shops are tiny and others have larger stands - like the produce/grocers.
It's definitely a nice place to visit to for groceries, food, and flowers!
