I used to eat often at Chung Gi Wah at Yonge and Finch, but it closed down recently (after almost 10 years at the supposedly cursed location! :'( ) and I loved it so much from there. Chung Gi Wah was a Japanese and Korean restaurant.
Anyhow, its just a simple little appetizer that's brought out before every meal, like the seaweed salad and cold rice noodles (can't recall the name of them at the moment) but i love it. And not every restaurant serves it.
If you know of one that does, please let me know :)
