Jefferson Hack handed out desserts that left some guests feeling dazed and confused at a dinner for Another magazine the other night. Among the 100- strong crowd were Glenn O’Brien, Jamie Burke, John Demsey, Leelee Sobieski, Maggie Gyllenhaal and Peter Sarsgaard. The editor walked around the penthouse of Milk Studios with a silver platter offering “space cakes” — bite-size Rice Krispies treats, red velvet cakes and brownies with an “herbal kick,” which helped some guests mellow out for the afterparty at Don Hill’s.
