Portillo's does not provide nutritional information on its products online as of 2015, but nutritional listings appear at FatSecret.com and NewsinHealth.info. These include many main products from Portillo's standard menu as well as a range of sides and cakes.
NewsinHealth.info publishes nutritional information for some of Portillo's products. It focuses solely on carbs, protein and calorie content and presents the information in a single long list. FatSecret.com showcases a more comprehensive listing of nutritional information, including the standard nutritional information label as seen on packaged products. Each product's details are located on a separate page found by clicking on the name of the product.
