Underneath the 8th Avenue side of the Columbus Circle subway station lives an underground food hall known as Turnstyle Underground Market. Bolivian Llama Party’s location in Turnstyle may be overlooked by the average commuter. But for any determined New Yorker, Bolivian Llama Party’s salteñas and chola sandwiches are well worth the hunt. Sometimes called Bolivian soup dumplings, salteñas are best enjoyed by biting off the tip and slurping up all the delicious filling through the gap.
