I was thrilled to receive my 180g box of Arnott's Cheese & Bacon Shapes. The taste of the biscuits was really quite sub-par. I'd been told that the cheddar flavour was superior, and I should have paid attention. These left my mouth dry and I was not within reach of any cola. I needed to call the nurse, who visits me every other day to wash me and check for bedsores, to bring me a cola on a day she isn't usually here. She's quite lazy, so I wasn't surprised when she refused. In any case, these shapes are okay, I would recommend you keep some drinks nearby.
