1970's thru 1990's - Victoria Station Restaurants, with at least three in Dade County
At least three locations in Dade County
They were a very popular chain of restaurants in railroad box cars in the 1970's and the quality seemed to decline with time.
The Dade County locations that I remember were:
NW 36th Street, Virginia Gardens, across the street from Miami International Airport
NW 183rd Street in North Miami Beach, just west of the Skylake Mall
Dadeland Mall, near the west end on the north side
