We used our Burpple Beyond one-for-one deals to enjoy two ice cream cookies for the price of one! The cookies were basically chocolate-flavoured biscuits, although don't expect them to be crisp since they are sandwiching a scoop of ice cream.
For our ice cream flavours, we ordered the 80% dark chocolate flavour, which was indeed pretty bitter as it's name suggested. Definitely not for those who prefer milk chocolate but for dark chocolate lovers, it's definitely worth a try! The Dark Gallery was fairly crowded right after lunch hour on a weekday, so it might be easier to get a table if you go for early lunch.
