Osaka Bar in Llankely Place in Potts Point really does look like it could be a casual eatery in Osaka, Japan. The kitchen, the lanterns, the lighting: it’s all right. Even our charming waiter who seems to have only been in Australia from Osaka for a few months added to the authenticity.
There’s a lot of styles of Japanese food that I think most folks won’t be familiar with: the wonderful octopus balls (takoyaki), like a pancake batter with chunks of tender octopus cooked in a waffle griddle, except instead of waffles, balls. There’s various kinds of 
omelette with artful swirls of Japanese mayonnaise and another sweeter sauce on top. Deep-fried skewers of things. Various other small plates (we didn’t try the sushi or sashimi).
All designed to go with beer! Or sake! Of which they have a nice selection (and the beer special that night, $5 for a Japanese beer, peanuts and dried fish skin, was a great bargain). I loved our meal here. The weird cheesy duck and eggplant gratin. The mound of rice with a simple omelette on top. A few deep-fried skewers (chicken thigh, lotus root, camembert), oh, and a stewed white radish with blueberry (!) miso and mince, an odd but tasty, very Japanese sort of dish.
Almost ordered too much food, but it was fine. There’s so much good food on this strip now… this is a good option, perhaps if you’re up for a more casual and quick meal. The 
outdoors seating area is great, and I said. This place has a lot of charm.
