Burgerfuel have a new passionfruit thickshake which you can now get for free with any burger. Their other shakes are good and have plenty of ice cream for thickness so I expect this will also be pretty decent.
One voucher per person, per visit. Not available for online orders.
Mate if this only applies to passionfruit thickshake, please mention that in the title.
Mislead me into thinking I can get a free chocolate thickshake.
