This winter, after you stand rinkside and watch your child circle Wollman Rink for a few hours (clomp, clomp, glide. . . clomp, clomp, glide. . .), treat yourself and your iceblock feet to something nice.  Visit PS 40 parents, Tal and Sue Inbar, at their Macchiato Espresso Bar and get yourself something nice, hot and foamy. Valid at the 666 Fifth Avenue / 52 Street location only. Expires May 4, 2013. www.macchiatocafe.com
