It's been a little slower than normal in the free food department this summer. Perhaps the tight economy is to blame? Luckily, the folks at Tangysweet are opening up another Red Velvet Cupcakery at their DuPont Circle location. To celebrate, they will be giving out free red velvet mini-cupcakes starting at noon on Friday until closing, which is 1 a.m. on Fridays. The cupcake recipes were developed by pastry chef David Guas, known for his work at the Passion Food group of restaurants.
