WASHINGTON (DC News Now) -- The H Street Festival is coming to D.C. bigger and better for its 19th year on Sept. 21. The festival is one of the District's most looked forward to as well as greatly attended. Traffic Alert: DC roads to close ahead of H Street Festival The H Street Festival is 12 blocks long and has 15 staging areas that have music, dance, performances, fashion, heritage arts, poetry and many other things. The festival started 19 years ago as a block party and has now grown into a 150,000-participant event.  "The whole point of the festival is to showcase our local businesses because this is a very unique and eclectic corridor," Wuiping Yap, H Street Festival coordinator, said. Tens of thousands of people means big business for many small businesses.

"I want to let the people know our food, our restaurant, and our food is, classic Chinese food," said owner Ike Ge.
