You should definitely walk the Village. Start at Union Square (if you are there on a Saturday, walk around the green market). Then head East on 19th (which is known as block beautiful) and then down 2nd Avenue. Stop at Mud at 9th and 2nd for a cup of coffee (best in the City) and then start heading West (explore 9th Street btwn 1st and 3rd, 7th Street between 1st and 3rd (stopping in at Butter Lane for cupcakes) and then west on 7th (stopping in at McSorley's Ale House). Head West through Greenwich Village and Washington Square Park. Keep heading West to the W. Village and play around. Head over to Hudson River Park, up Commerce Street (Commerce is an amazing restaurant for a late lunch/dinner) and then up to the meat packing district (see the Gansevort Hotel, Pastis, the 14th St. shops, etc.). Then walk up the High Line (at 14th and 10th Ave.). These are just some of the highlights - there is nothing like spending a day in the Village.
