MAMAOH's uncomfortable seating didn't hamper my dining experience, but it is worth noting that this place isn't good for people with tender backs as the booths are rather stiff and benches are oddly bolted down.
Don't come here for the traditional food - it is relatively uninspired but just okay if you just need some basic Korean food. I've only gone here for the fusion, as that's what they seem to emphasize.
First time there I had a bulgogi burrito which was surprisingly very tasty. Bulgogi and rice were a given, but the mozzarella and kimchi really pull it together. It was both delicious and filling, if not a little pricey. My girlfriend had the creamy champon (or jjampong? if referring to the korean version), which to me was extremely tasty. The cream twist works perfectly with the flavor.
The second time, I had the udon salad, which was refreshing and tasty. My girlfriend had the tofu soup which she said was okay, but not great.
They do have some issues with service here - primarily just being a little slow. I'll give them a bit of a pass as a new restaurant, but don't expect anything to come out quick here unless they aren't busy. Prices are a tad higher than I'd expect, but nothing beyond reasonable.
