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).
Have you ever had Uzbek food? Me neither until I went to Nargis Cafe. It's kinda like middle eastern food mixed with Ukranian food. It's so good and so inexpensive.
Great barber shop. Been there for years. Used to be upstairs, moved downstairs. A New York City staple. Need a haircut? Go here... Oh yeah, and they have karaoke. Enough said.
Seasonal salads, sweet and savory treats, and great coffee. It's probably my most common lunch spot when I work from home and they also offer catering if I'm too nervous to cook but want it to feel homemade.
