Tasti D-Lite, the New York-based “low fat frozen dessert” chain has opened its first D.C. location at 2029 P Street NW. We are still not totally clear as to how this frozen dessert is low fat, and how most servings clock in at only 100 calories with no artificial sweeteners — we hope this isn’t like some Seinfeld episode with deceptive frozen yogurt, especially since it turns out that fatty foods are addictive like cocaine. After all, we’d hate to end up looking like Jerry Seinfeld photoshopped on Regis Philbin’s body.
