From http://cinematreasures.org/theater/4655/ :
"Easily one of the finest theatres erected in 1950, the 2,200-seat Carib was opened December 22, in one of the city's most fashionable shopping districts. As such, it commands an excellent admission scale...In keeping with its name and location, a Caribbean theme prevails throughout the theatre. The front bears a huge map of the area done in raised porcelain, the open-air patio-foyer has a tropical atmosphere, and the auditorium is designed with a distinct under-sea motif...From the large main foyer, where a wide candy bar is situated, an escalator moves upward toward the mezzanine. This is enclosed with glass in the front to afford a full view of the patio-foyer entrance, wherein are found flagstone walls and floors, a huge antique mirror, and flying birds made of plexiglas...There is a television lounge on the second floor and another set in the foyer...In the auditorium, the cartouche design on either side of the proscenium arch signifies a floating sheet with mystic designs of undersea life and is made of plexiglas and ornamental plaster with indirect lighting. The proscenium arch has bases of Octopus-design which, when indirectly lighted, make the proscenium appear to float in mid-air."...The Carib apparently did not have full stage facilities. The area behind the screen is simply described as "platform"...The orchestra floor has three wide sections of seats, but curiously, only the center section continues to the rear. About two-thirds of the way back, the left and right sections suddenly divide into two sections with a center aisle. The seats in those four rear sections also appear to be different from the reset of the orchestra seats."
