Yet another restaurant is to open at 4123 24th St: Bistro 24. So far there's just a sign in the window that says "Coming Soon: Bistro 24." No building permits have been filed. The domain name bistro24sf.com is currently parked on godaddy.com. And the beer and wine license is still held by the previous tenant, Stefano Coppola of Lupa.
Just speculating, but all this looks like how Mr Coppola opened the last business here. Could it be that City Grill is no longer for sale?
