Things I really like:
Places that do just one thing but do it very well.
Self-serve.
Real frozen yogurt that actually tastes like yogurt.
Razzy fresh combines these three virtues. The yogurt is delicious (I'm partial to the original and raspberry), as are the toppings (fresh berries, mango, kiwi, etc.). At about $0.50 an ounce it's a bit pricey (I can rarely keep my portion under 8 oz.), but worth it considering the quality.
