nyc is pretty pet friendly. they are used to people with little dogs in their arms. they have tons of restaurants with seating outside. most upscale stores have pet friendly policies if you carry them. check out china town for shopping. they have alot of outdoor vendors with great stuff. especially, if you like faux bags. (fendi , louis vuitton , coach, gucci + any designer under the sun) sat/sun are the best days to go to china town. try the magnolia bakery near chinatown. featured in sex and the city and growing up gotti. they have the best cupcakes you will ever sink your teeth into. totally worth the trip. have your hubby stand outside while you go in! central park is dog friendly with a dog park. take the carriage ride you will luv it! nyc pet stores are awesome. check the yellow pages at your hotel. they also have plenty of doggy daycare. ask your concierge. without your doggy go to ellens stardust diner on broadway. awesome food and the waiters sing! prices are good too. carmines near broadway has the best authentic italian in the usa. trust me on this one my dad is an immigrant from italy. go for lunch. the portions are smaller and it's less expensive. a favorite hangout for celebs i have seen howard stern and christina applegate hangin out there. for theater go see the color purple. the best i've seen ever and i'm a theater person. worth every cent. the tourist trap at top of the rock (top floor at rockefeller) is amazing. if you go shoot for a clear day. the view is nothing less than spectacular. i'm sure you found a hotel already and public transit & cabs are pet friendly. be careful the people traffic on the sidewalk can be pretty intense. carry your furbaby on crowded streets. any questions feel free to pm me. i go to nyc frequently. have fun!!!!!
