As far as selection goes, Top Food & Drug in Woodinville is one of the best grocery stores in the area.
They have a fabulous bakery, a great wine section, fresh produce, and a really nice garden store right out front with plants and flowers that rival Molbak's.
There is a supervised kids' play area if you want to drop your tots in there to play (versus having them beg for all they see in the store) while you shop. It's clean and light-filled.
Top is tops!
