Bill Bryson’s travel books, especially A Walk in the Woods and Down Under.
Terry Pratchett’s Discworld series. Like the whole thing. Can’t pick a favourite.
David Sedaris - Me Talk Pretty One Day
John Birmingham - He Died With a Felafel in his Hand
Not sure if it’s in your list, but the hot dog places were immensely popular and quite cheap when we were there a few years ago. Bæjarins Beztu was very tasty. Ate hot dogs with crispy onions and remoulade A LOT when we got home to recreate them. Even if you can’t take them with you during the day tours I’d recommend trying it out anyway.
