I suppose it might get boring if you fly OZ frequently, but I recently flew OZ as a once-off (four sectors) in Y, and thought the food was the best Y food I have ever experienced. Ex-ICN on long haul it is the ssambap as noted above, into ICN long haul it is the bibimbap. Both were excellent: fresh, tasty and different from the usual slop in Y for other carriers. But the outstanding meal was the second meal (dinner) on our flight into ICN (from SYD) - spicy octopus with rice. Amazingly tender and delicious. Not at all chewy like you would expect octopus when served at the end of a long flight. Very generous with the drinks as well!

(There was an alternate choice of meal each service, but I always selected the Korean option.)
