If you're not into the college bar/pub type scene, I totally recommend this place during lunch or dinner hours. The Nines has some of the best pizza in Ithaca. I totally miss living there, and being able to go grab a slice whenever I feel like it!
The atmosphere here is pretty cool too. The Nines name comes from the fact that this building used to be Ithaca's #9 Fire Station. They still use some of the pulley systems to send things between the 1st and 2nd floors, and it's just pretty nostalgic feeling. They also have great outdoor seating for the warmer weather months.
If you're looking for a great place to grab great pizza, The Nines is it when in Ithaca!
