Between the years of 1904 and 1944, the Greek Revival–style mansion that now holds Eric's Porter - Haus was home to former Waukesha mayor Isaac Lain. Today, it's a bustling supper club where servers make the rounds to multiple dining rooms, one of which is equipped with a fireplace lined with fresh cookies for Santa. Chef Chris prepares Old World specialties such as black forest schnitzel made with natural range-fed veal. Another specialty is steak; tender filet mignon sizzles alongside 24-ounce porterhouse cuts. Bottles imported from Germany, Australia, Italy, Spain, and California also make appearances on the wine list.
