At Biergarten, the fish tacos are built around crispy fish tucked inside a combination of hard and soft shells, with guacamole layered between for extra richness.[5] The twist here is the structure of the taco itself, using a double-shell format more often seen in mash-up creations, which gives the dish a playful, indulgent feel.[5] Each bite brings crunch from the outer shell, softness from the inner tortilla, creamy avocado, and warm fish, making it feel more like a bar snack reimagined as a full taco. Diners frequently point out the creative construction and the way the guacamole binding keeps everything together as part of the appeal.[5]
