I thought Moko was meh. I got the chicken bulgogi. I liked that the chicken was charred, but it had somewhat of a rubbery texture. The dish itself also just didn't have much flavor - just chicken, white rice, green onions and sesame seeds.
My girlfriend got a custom ramen with just noodles (we shared). It was fine.
The portions were on the small side, so I ordered a beef gyoza because I was still hungry. It was really, really greasy. It gave me a stomach ache afterwards. Plus, it was $5 for very little food. That experience definitely solidified Moko as a two star place in my eyes.
