Thank you, Barb and good morning everyone. Thanks for joining us for our fourth quarter and full year 2023 earnings call. I'm happy to share that we had a great fourth quarter and ended the year on a high note. In the fourth quarter, total sales increased 24.5% to approximately $188 million. Same-restaurant sales grew 4.4%, on the back of transactions increasing 1.3%. Restaurant-level adjusted EBITDA grew 42.7% to $46 million and restaurant-level adjusted EBITDA margins expanded by 310 basis points to 24.3%. For fiscal year 2023, total sales increased 15.8% to approximately $680 million. Same-restaurant sales grew 5.7% and we ended the year with average unit volumes of $9.1 million per restaurant. Restaurant-level adjusted EBITDA grew 24.7% to $165 million and for the full year, we expanded restaurant-level margins by 170 basis points to 24.3%. And importantly, we grew operating cash flow by 24.4% to a record level for Portillo's. Let's dive into the factors that drove the success. First, we were operationally on-point. We believe the best way to drive revenue and traffic in a sustainable fashion is to give our guests the outstanding experience we're known for and they've come to expect. In the fourth quarter, we did just that. The result was strong revenue and margin performance, multiyear highs in overall guest satisfaction, and a current Net Promoter Score of nearly 70, outperforming most of our peers. We know the play, we serve abundant, delicious food at a fantastic price in an engaging environment. This is the number one way we create value for our guests and keep them coming back. In Q4, we flexed our multichannel muscle extremely well. We excelled in dine-in, our drive thrus were hummin, pickup and delivery orders were flying off the shelves, and we did a great job growing our catering business. For example, in 2023, we invested in dedicated catering resources such as a new concierge service to provide our guests with a high-touch ordering experience. We also strengthened our ability to handle large-scale catering events. For example, we serve holiday meals to the frontline workers of a major airline in both Chicago and Arizona. The overarching theme there is that these investments are driving strong catering sales and will help us to continue to grow this channel. Today, catering represents only about 5% of our overall revenue. We know it can be more. We're excited about the opportunities to grow this channel, by marketing additional catering occasions and expanding this channel across our new markets. So speaking of marketing, in the lead-up to the holiday season we ran an advertising campaign in Chicago that brought the sites, smells and sounds of Portillo's to the forefront. Instead of using discounting to drive traffic, we simply reminded fans in our largest market why they love Portillo's. If you haven't seen our ads, we have one linked on our Investor Relations website and you can see for yourself how a simple message like this can work as a traffic driver. And as we move forward in the New Year, we're going to continue to leverage traffic driving tools and initiatives. One that I'm excited to share is that we'll be adding two new salads to our permanent menu soon. As you know we take menu innovation very seriously at Portillo's. We don't just add items to add. They have to fill a gap in the menu, makes sense operationally and most importantly, be Utterly Craveable. Portillo's already generates more than $650,000 in salad sales per restaurant, per year, with our beloved Chopped Salad is the best seller. Based on consumer and competitive data, we know we've got space to add more variety to this already Craveable Menu category. So we created a Spicy Chicken version of our signature Chopped Salad. We've also tested a Chicken Pecan Salad with a new Honey Peppercorn dressing! Like all of our salads, these are also made fresh to order and you can customize all the ingredients, however you want. Both test salads are selling really well. And we look forward to rolling them out system-wide soon. Now let's pivot to development. In 2023, we opened 12 restaurants including six in the fourth quarter. That 12 includes, eight planned 2023 restaurants as well as the four carryovers from the prior year. This is the most we've opened in a single year. And I'm excited for what this means. And what we can do in the future. We've already got a lot of momentum heading into 2024. And you can expect it to be another strong year of growth for us. We've committed to at least nine new restaurants in 2024 pipelines, five of which are already under construction. And by the way, we self-fund all of this growth. Our new restaurants generate cash flow immediately. And we put all that cash right back into the business, to fund further expansion. Now as for unit economics, I've been told that everyone is sick of me bragging about the Colony restaurant in Texas. So let's talk about some of the other stars of the class of 2023. I'm extremely happy with the results coming out of our growth markets in particular. Fort Worth, Texas! and Claremont Florida have both opened strong out of the gate and especially impressive with our new efficient kitchen layout. We also opened our second pickup location in Rosemont Illinois. We continue to learn a lot from this model. And we were and we're excited about its potential for Portillo's, as we continue to grow. Remember that, this model has everything except a dine-in capability. So it's essentially a drive-through. We delivered a strong finish for the class of 2023. And we're looking forward to entering the Houston market in 2024. All told, we're really happy with the quarter and how the year ended. We executed on the fundamentals of our business and invested incrementally to drive brand awareness. In 2024, we will continue to flex drive, traffic driving tools, driving success first and foremost by being operationally sound and protecting our value proposition. We're just building on the factors that have made Portillo's great for 60 years. We continue to execute against our playbook, providing a great experience and great food, at a great price point is not ours -- are not our -- not so secret-sauce. It's how we drive the kind of financial results you saw from us in 2023. With that let me hand it over to Michelle.
