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).
Nothing is more quintessentially New York than a diner. This eatery not only serves excellent, traditional diner fare, but does so in an eclectic environment that mixes Baroque decadence with Midtown grit.
This is the place where I ate my first burger just 2 hours after I arrived in 'tha hood' I loved the place immediately because of the supersweet employees. And the fact that they have al this vintage machines in the place: like an old COKE machine and a cigarette machine as well as a jukebox from the sixties. The fact that they serve ALL DAY LONG BREAKFAST really made me happy, probably because I lived in Berlin before I moved here and there people are endlessly chilling and having breakfast the whole day long anyway! On wednesdays Wally organizes film evenings with funny nineties classics and on thursday evening you can eat a 5 dollar burger menu. While eating your inexpensive burger think of Wall.E.
If you are in need of a moment of solitude, this is the place. On my first visit I was in awe of how time seemed to stand still inside. It has now become a sanctuary from the city when I need the pace of life to slow down.
