I heard good things about the main Matt's Big Breakfast chain, but this one was very mediocre. Maybe it's because airport food is never as high quality as outside food, I'm not entirely sure.
We had the Sonrisa Burrito, which was decent. I liked the thin tortilla that they used and the salsa was a nice addition, but the burrito was very oily and dripped a ton as we ate it. Their potatoes were also undercooked and had a weird texture to them...
I'm usually a huge fan of breakfast burritos, but I wish I had skipped Matt's Big Breakfast and tried Sweet Republic next door at the terminal (even if it was 10 in the morning!).
