DeKEFIR is a great place to go for an organic, healthy-ish dessert!
It's a difficult place to find as it is located in an underground shopping centre.. but it's worth the search. The yogurt is made of kefir bacteria which aids digestion. Despite the creamy and sweet taste, it is low in fat and calories (according to the staff). It's a little bit pricier ($4.50 for a small cup), but well worth it. They provide numerous fruit and cookie toppings.
