Having the experience of owning and running a coral reef aquarium (and frequenting this particular shop about once a week) - I was sad to hear it closed it's doors. Their reef display tank was always amazing. These pictures were taken from PetCo at Union Square (I also used to go there for my saltwater needs).
Chinatown in general, I've lived in chinatown on and off for my entire time in New York and i never tire of it’s textures, smells, artificial lighting and grime. There's some amazing things to happen upon there as you trek about your way, a true city experience. Love this little culture shop Aeon, gems of records, art and ephemera tucked away like most good things are.
Another Gramercy all-star, I really like this place, you need a reservation or early arrival, sitting in the bar is always fun and the food is amazing!
