Hey Martin, you can start at Bergdorf on 5th Avenue around 58th Street and then make your way over to Bond (2 blocks over). Then head back down 5th to pass Takashimaya, Bendels, and Saks. This will cover many of the niche scents on your list. If you stay in Times Square at the Days Inn or Milford Plaza (both my regular locales and both quite reasonably priced), it's a 15 minute walk over to 5th. At Times Square you'll have a Perfumania and Sephora to browse. Once your done with these, I recommend heading over to the Le Labo boutique, Barney's, and a quick trip over to Brooklyn to visit I Hate Perfume. If you have time, check out Malin + Goetz, New London Pharmacy, Caron, LAFCONY, L'Artisan's new shop, Aedes and Comme des Garcons. For discount fragrance shopping, you'll find a TJ Maxx at 620 Ave. Of The Americas. I'm sure there are other places to shop, but these are my usual haunts! Have fun and good luck!
