Oddly enough, when researching the Blue Mountains, the fine dining places didn't appeal that much to me. I think Ashcroft had a decent sounding menu (but in the end couldn't get a walk-in table on a Saturday), Darley has accolades (but is expensive) and Silk's wasn't all that interesting (other than the lamb brain and sweetbread entree). After rejection from Ashcroft and no availability at Pins on Lurline (with its udon and Italian menu), resignation hit and the car was directed toward Sanwiye.
I would never have really considered a Korean restaurant in the Blue Mountains, as this reminded me of the token Chinese restaurants you find in small rural towns all over the world, with the standard dishes and sauces and MSG (much like I expect the South Park City Wok restaurant represents). However Sanwiye had good ratings, there didn't seem to be many other options, and the other ones were probably already full.
I've had the cinnamon drink sujeonggwa at Bistro K before and so eagerly ordered it again. It was extremely potent in cinnamon. Perhaps a little too much.
- Mandu (crispy lightly fried half-moon dumplings) $10 - nicely fried dumplings with thin fillings and a soy to add extra flavour;
- Duk-bokki (rice cake & vegetables in sweet & spicy sauce) $16 - an excellent textured gooey set of rice cakes in a mild chilli sauce;
- Spicy Seafood Noodle Soup (prawn, calamari, fish cake, carrot, capsicum, onion, sliced cabbage, mushroom) $13 - beautiful broth with (what may have been instant noodle) ramen cooked to retain spring, some average pieces of seafood (very small prawns, but I suppose you don't expect much for the price up in the mountains) but an excellent warming soup that tastes exactly how a Korean/Chinese noodle broth should. They asked if I wanted spicy and I said yes, but it wasn't too much.
Other than what was tried, the platesized pancakes looked like a good bet also.
Overall the prices are reasonable, the food is good quality and it appeared to be a family run place (Australian male and a Korean female heading the show). Well worth supporting. If you are dining for 2, I'd try to call and book the little table at the front which affords more privacy and a view of beautiful lighting and flowers.
