Just got a Bday voucher in my email. I signed up to their frequent diners about a year ago, so perhaps this is a new promotion?
Signing up is free - 30 bucks would get you a rump steak meal + a drink. I usually get the double combo and share with my gf when I go there. 50 bucks for 2 people, good value and absolutely yummy!
Best steakhouse in Sydney hands down. (They are nation wide, the one up in gold coast is also very yummy!)
And by nation wide, OP means there are 5 NSW locations and 1 QLD.
