This time round they're holding a massive wine tasting in Paddington Town Hall
Not only does an afternoon of wine, saké and spirit tastings accompanied by snacks from Mary's sound like mad fun, but it will also make you look cultured and fancy when you're tagging yourself alongside 100 of the most interesting wines on the market right now.
The idea of Mental Notes is to create a wine tasting experience devoid of pomp and exclusivity and instead draw people into the wonderful world of wine. Basically it's a house party with the best drinks list you've ever seen.
It's hosted by Joel Amos from DRNKS, and Jake and Kenny from Mary's and the Unicorn and there will be a bar with a wine list that changes every hour, plus a bottle shop so you can take your favourite home with you. The afterparty will be at the Unicorn just down the road.
Even better news is that this year tickets are on $40 a pop and they're splitting the afternoon into two sessions – noon-2.30pm and 3-5.30pm – or you can grab a rare ticket for the full day if you get in early.
