Pananas Restaurant continually surprises diners with a selection of upscale entrees that change with the season. The spring menu promises fresh options such as the grilled salmon, which is sautéed in creamy pesto before it comes to rest atop bitter greens and risotto-stuffed tomato ($21). Ensconced in an au poivre crust, the 16-ounce bone-in Delmonico steak frolics through sprinklers loaded with balsamic grilled onion and gorgonzola cheese sauce ($28). Pasta options abound, including farfalle aglio e olio, which adds zing to bow-tie pasta with breaded chicken and broccoli rabe sautéed in extra virgin olive oil, garlic, and crushed red pepper ($15). The stuffed artichoke Francese brims with sundried tomatoes, boursin cheese, and lemon butter sauce ($8). Since main courses rotate seasonally, chefs can take advantage of the migratory patterns of vegetables to guarantee access to the freshest ingredients.
