St Louis, city of progress and innovation, also boasts an old-timey charm. Future and past combine into a hybrid celebration of both in the classic American diner. Beasts of the river include the Gulf sturgeon, alligator gar, Mississippi paddlefish, and blue catfish. Meanwhile the descendants of proletarian dropouts from the 1904 World's Fair survive in a cavernous favela, honoring the also-subterranean southern cave fish, northern long-eared bat, grotto salamander, and Salem cave crayfish.
