A month or so ago, the hubby and I tried BBQ Chicken at Diamond Jamboree (this Irvine multi-cultural plaza in Irvine). We've taken a few friends and family here since then. It's a great Korean restaurant that stays open late and is really affordable.
They serve fried chicken prepared with olive oil. Their spicy sauce is the best - sweet yet tangy hot. Other items to try on the menu include their fried rice and french fries. Yum yum!
