I remember going to the Velvet Turtle in W Covina for ‘special’ Sunday Buffets….but it sure wasn’t ‘roadfood.
The closest thing to BBQ from the South was Dan, Dan, The BBQ Man, built in an old Foster Freeze stand out on Valley Blvd. in Bloomington CA. His cookers are on the sidewalk in front of the place and a few picnic tables are there too.
