I am coming to NY in three weeks with my sister, both in our fifties and our daughters, late twenties. Can you recommendss ome bars near 60th Street 2nd/3rd Avenue? We are eating at Serendipity one night so I thought we could have a look at some bars in the area. Also we are going on a Dyker Lights tour which drops us off at Union Square. Would it be better to go to a couple of bars here or go on to Bleeker Street in the Village?
