Here's the statement from the Gu's website:
We have permanently closed our Buford Highway location, so in the mean time, please visit our Gu's Dumplings location (www.gusdumplings.com, @gusdumplings, fb.com/gusdumplingsatl) at Krog Street Market in Inman Park, set to open in the middle of March. We are looking for a new location for Gu's Bistro to continue to provide the BEST Chinese experience in Atlanta! Feel free to check the website for updates, and be sure to follow us on Twitter (@gusbistro) and Facebook (fb.com/gusbistroatl). Of course, you can always email us at firstname.lastname@example.org. This is not the end, it is the beginning of something even better! Thanks for your continued support!
