Holbox is a Mexican seafood stall inside a food court, about a 15-minute walk from BMO Stadium. It serves kanpachi tacos, octopus tacos, seafood ceviche, and uni tostada. You take a number, sit down, and the food comes out within 10 minutes, with house-made hot sauce available at the self-serve bar behind the ordering counter. The line is long and the portions for each menu item are small.
