Byron lets you customise a burger with priced extras. Dips and sauces, from BBQ and ranch to truffle aioli and hot honey, are priced singly or two together, with gravy and cheese sauce a little dearer. An extra patty, pulled beef or chicken is the dearest add-on; bacon, cheese, guacamole or vegan bacon come next, and mushroom, crispy onions, jalapeños or pickles are cheapest. The cheese can be swapped for smoked cheddar, blue, goat's, Emmental or vegan cheddar, and the bun can be changed for a gluten-free one or a salad.
