I went to the cafe for lunch - gorgeous spot by the water. Food was lovely, and the service as expected. Good selection of food to share or mains / desserts to eat by yourself!

Beautiful autumn day, lovely setting inside the restaurant - we had really high hopes... but they didn't work out.
After sitting down we waited 15 minutes for the menus, after which we had to ask for them. The staff were pleasant but mostly ignored serving anyone. They would pop their head into the room and assume everyone is fine without actually coming past the tables. Our waitress was so nervous it was hard to understand what she was saying. We tried to be as friendly as possible, but still the service wasn't professional at all.
The food was nice, but not amazing. It seemed like most of the mains came with some version of ratatouli. We didn't observe any creativity in either taste or presentation.
It wouldn't be too bad if this was a cafe, but as the Boathouse restaurant markets itself as one of Australia's best fine dining places, our expectations were of a different calibre.
All 2 stars go to venue view and ambience. Nothing else would bring me back there.

This place is on the side of a pretty little river, have only been to the café however the restaurant I hear is fantastic also, . They also have little row boats you can hire down at the river, which I have never done but really want to.

This is such a lovely spot. Always always busy on the weekends, but why wouldn't it be. Great coffee great food and a great view. Also a great place to take the kids, plenty of room for them to run around.

For my birthday, my wife booked lunch at the Studley Park Boathouse after reading a review. We were also glad to hear that they were also willing to accommodate our thirteen month old. When we arrived the service was courteous and seeing that we had a child, quickly gave us menus, knowing that we didn't really have much time. I ordered the poached sole and my wife had the salmon with a shared seafood entree.
When the food came, I think the chef was trying to be overly ornate. The entree was ambitious - too many flavors, too many textures. It felt like s/he was trying to show off all his/her skills in a single dish. Our mains weren't any simpler. My poached sole looked like it was a fillet covered in damp newspaper surrounded by cold cubes of panacotta, served over a bed of shredded mango, cucumber and sweet chili sauce. You get the idea - too much soft, crunchy, spicy, creamy being blended together. My wife's salmon was served over a gooey risotto that was both over and undercooked - the odor carried a hint of charred rice, like it was left too long on the stove but had far too much texture to be cooked sufficiently.
We left our meals half eaten and raided the pantry when we got home. Pity because the restaurant has a great view.
