I have been to BBH on S. Decatur many times for lunch.  I have always enjoyed the food and never have had a complaint.  Today I happened to look at the ceiling and was totally disgusted.  There was a dead spider hanging from an air vent that kept swaying with the air of the ceiling fan.  The ceiling air vents are full of dust.  The ceiling tiles have evidence of past water or liquid leakage damage and they are also infiltrated with dust and dirt.    I shouldn't have looked up. After I saw the spider hanging, my appetite went away.  I felt this filthy restaurant belongs to a third world country.
