@pooriggy may I suggest this?
Walk across the GW,then grab City bike,then head down Greenway..stop by intrepid museum look around snap some selfies then not far from intrepid,
Go to meat packing district,i'm sure you know this rode around check our some cool stuff The Rapha not that far just around that district..
and then head down to GreenwichVillage,
Do you like Bob dylan?if yes then you gotta visit MacDougall street in Greenwich Village. Beer and lots of good stuff..with city bike,you have more flexibility you can ditchoose them anytime and anywhere.
On your way back,back to meat packing again and take a stroll on highline trail about 1.45mile start from meat packing district on Gansevoort street and 14th St near by greenway,it's a elevated concrete rail trail a very nice walk you can ditch the city bike here,
Trail ended at 34th street near javits center,from here get on city bike again,head towards times square take selfies with naked young ladies or just take greenway back to GW,if you have time,go to central park loop,then back again to greenway finally if you really hungry,stop by at Dynosaur BBQ right off 125th i'm pretty sure they serve beer,tho i'm not sure but this is a quite famous joint just before Fairway supermarket,or skip that,near that block there's bar/restaurant nearby,just like Jmanic said.
Have Fun and be safe.
