The key word about Oriental Express is "express". You'll get your food quickly, and in styrofoam, bc they don't really care if you stay or not.
I only go for their jajangmyun, which is actually decent. It's better than Cafe Ga Hyang's jajangmyun by far. You can tell the noodles are fresh. The sauce could use a lil more meat, but it's not watered down.
There is an unpleasant sour smell when you walk in. I couldn't pinpoint it, but it certainly didn't make me want to stay any longer than necessary. It didn't used to smell like that, but it appears the restaurant is under new ownership, and they've let some things fall through the cracks.
I'd still come back but only for take out orders. They have a secret Korean menu that you should ask them about.
