Tria opened this first location of its now citywide bar and café chain in Rittenhouse Square in 2004, based on the trinity of beer, wine, and cheese. The menu has a rotating selection of approximately 16 artisan cheeses at any time, ranging from Missouri sheep’s milk to Spanish goat cheese. There’s also heavier fare like truffled-mushroom sandwiches and smoked-duck salads. The dishes were designed to be paired with the daily microbrews that may include Pennsylvania Pilsner or Belgian ales at any given time. Ditto on the ever-changing list of wines from small producers.
