We have been here a couple times now, taking advantage of their winter discounted lunch menu.
They are open 7 days a week for lunches, which is great as a lot of wineries down that way are not.
The portion sizes are perfect for lunch and the food is quite nice (though I'm not sure if the Chef uses salt as most dishes just seem to need a little kick in the flavour department).
The white wines are lovely (my partner likes their Heathcote reds) and the views of the vineyards is the perfect setting.
They have a coffee table and couches set up in front of the open fire - a perfect spot for the kid's to do some colouring-in whilst we enjoy our meal, and they are happy for the kids to run around outside and enjoy the grounds, and play spot the Kangaroo! (Overseas tourists would love seeing the Kangaroos over lunch, I'm sure!)
