This can not be real. Need a DC anon to go to 17th & Q streets and confirm.
Yeah, I found it. It's on the NW corner of 17th & Q streets and it has a Christmas tree outside. However, a photo of daffy the duck is on top and no U.S. flags. Plenty of rainbow flags though.
I just searched the restaurant name and it has a photo of the restaurant with the Christmas tree out front. Again, a picture of Daffy the duck on top and many rainbow flags. The tree with the Bidens is fake and gay.
