It's really a fantastic idea and what seems to be a great business move. I think people will love it. What's great about Portos is that they have a lot of cheap and "on the move" kind of food, all of which taste great. Their big hits are potato balls stuffed with meat or veggies, empanadas, and various sweet and savory pastries. I just looked up prices at my closest location (which will probably be cheaper than whatever prices will be at DD...) but currently the classic potato ball is $1.25, a chicken empanada is $1.39, a spinach feta empanada is $1.19, an apple strudel is $1.55, and a butter croissant is $2.09. They also have breakfast and lunch/dinner sandwiches and salads (between $6.25-$8.99), and the location near me does plates with chicken, pork, or steak with rice, beans, and plantains ($9.89). They also have coffee and smoothies. I can see them being a big hit with people who just want to grab something quick before going into the parks or while jumping between the parks in the afternoon, and the stuff is great for bringing back to a hotel at the end of the night for a late night snack or a quick hotel breakfast. Plus their cakes are gorgeously decorated and are great for people who want to buy a cake to celebrate a special occasion. Also... you literally can't beat those prices. It's one of the few places in LA where you can get a sandwich, dessert, and a drink for under $10 a person. Their "normal" locations already get packed, but I can see the lines constantly out the door, especially in the morning, as people run in to grab a guava and cheese strudel and a cold brew, and maybe a cookie for the kids, on their way into the park.
