Located at the southern end of the Turnstyle Underground Market at the Columbus Circle A/C subway station, Merchants’ Gate is a rather small beer/cocktail bar adding variety to the dozens of food/coffee shops already in Turnstyle Underground Market.  The bar offers about 10 draught craft beers and another 10 mix of craft and generic bottled/canned beers.  The bar opens daily at 11am and can run as late as 2am daily, though some evenings it may shut earlier than that because Turnstyle Underground Market doesn’t get a lot of foot traffic late night.  The bar is another example of a cashless business, so be ready to pay with credit/debit.
