This place is amazing. It's a short walk from our apartment and has an amazing happy hour including cheap guacamole and $4 margaritas. We can spend an hour or five hours here at a time because the environment is so casual, welcoming, and the food is just damn good. Get the lengua or the camaron al mojo de ajo tacos or hongos and rajas con papas if you are vegan.
Erie Basin is a really wonderful little shop full of old, creepy and beautiful things, such as Victorian mourning jewelry (some with hair in it), Freemason masks from the 1900's, tiny children's rings from the 1700's, and all kinds of other treasures. It is really as much a museum as it is a store, and all of the items have a haunting and unique aura.
The best part of the new Whitney Museum is the view in all directions from the terrace - and also from the staircase facing West. I'm afraid it upstages the Art.
