If you pick up a copy of The City News there is a voucher in there for $3 off food purchase from most of the participating vendors in the Wintergarden.
So you could buy a $4 burger and pay $1 + voucher.
A new edition newspaper comes out mid this week so be sure to swipe a hard copy before they go - alternatively attached pdf from the city news site can be printed.
pay 50c and get a gloria jeans coffee?
