Price drop on Zomato Gold Annual Membership stacks with 20% off from referral code = just $28.80 for 12 months. Price is consistent for all three cities (Sydney, Melbourne, Brisbane). Similar to last year's Black Friday promo price.
Not sure if it is a temporary thing due to COVID-19 but if so, now is a good chance to get your membership as restrictions begin to ease and in case the price goes back up.
The list of restaurants has definitely shrunk and I can't see any 1+1 deals in Sydney - restaurants generally offer a flat 10-30% off. However, there are some decent spots in the CBD that don't usually offer discounts on EatClub or otherwise (my faves are Kobe Wagyu, Chefs Gallery, Spice World and Shiki). At this price, you can make your money back in just a handful of visits so definitely worth it imo.
Note: Currently referee gets 20% off but referrer does not receive any free months.
10% off doesn't seem like much, I really hate using discounts or apps when dining out. 30% would be worth it, and the Adelaide list isn't too bad but I can't see what the offers are.
