These are my fave underground spots... they are literally underground! =) Both are semi-exclusive places which would normally be a turn off, but the drinks are great and the music is very good especially at Submercer.La Esquina (106 Kenmare Street) is under a taco stand. Get past the bouncer, go through the kitchen, talk to the hostess & you’re there!Submercer (147 1/2 Mercer St. @ Prince Street) is under the restaurant Mercer Kitchen. Phone: (212) 566-6933
