What good AYCE Korean BBQ also has great banchan?
You need to head on down to Star King BBQ. They have THE BEST meat ever! I don't think I've tried a better cut of beef. They have a Premium AYCE BBQ for $34.99 and the ordinary AYCE BBQ for $17.99. (I think the difference there is you don't get any Prime Rib Eye or their other nice cuts)
If you don't want the AYCE I suggest checking out the Jidori Chicken and the Certified Piedmontese Beef.
Their banchan is SO GOOD. They have a large variety of banchan. I'm told most places don't have too large a variety because of the time and labor behind making these fermented and cooked side dishes. My favorite banchan was the sea kelp tossed in a light mayonnaise (Lower Right)
Try the Sweet Potato Noodles Dish (Japchae)
and the Seasoned Acorn Jelly (Dotorimuk)
for sure too if you're looking for yummy appetizers.
re: Butter Fight
My point exactly... the best banchan of an AYCE Korean BBQ restaurant.
While I have yet to go to Park's, my favorite non-AYCE Korean BBQ at the moment, is The Yellow Cow in Gardena. I was stuffed. Some of the banchan were unusual (for example, using blueberries with other flavors that I wouldn't think to combine). The portions seem quite generous to me.
