Liberty Park down by the WTC site is open again (probably has been for a while, but I haven't been downtown in months), and the pre-September 11th vendors all seem to be back. Those falafel guys and, most importantly, the Halal chicken and rice guy that always had a line 20-30 people long.
The caveat: the chicken and rice is nowhere near as good as I remember. He's down to one helper, and he also now sells gyros (he used to be strictly chicken and rice), so he's probably not doing anywhere near as well as he used to.
Just thought some of you might like to know.
