What's the coolest place to chill out on a hot afternoon or evening?  Why, it's Strawberry Fields, the trendy new self-serve frozen yogurt store in Morristown, N.J. The restaurant is located on popular South Street, just blocks away from The Green. Strawberry Fields offers your choice of yogurt flavors and toppings. You serve yourself a treat that's not only delicious but healthful.  You can feel positively virtuous as you eat a bowl brimming with frozen yogurt and nutritious (or decadent) toppings at one of their tables, or take it out to stroll the sidewalks of this hip town.  If you bring your dog, Fido will be offered water from a huge dog bowl outside as well as a dog treat on the house at this pet-friendly establishment.
