It's open 24/7 and they make/serve really quick, which is really convenient if you're a night owl (hence the name Owl of Minerva i'm guessing), but i found the food to be pretty bad.. Got the bulgogi which was soggy and drenched in oil. My friend got the pork bone soup and said it was good, definitely not breathtaking. Portion sizes were average and price is pretty cheap.
There's so many amazing Korean restaurants in the area i wouldn't bother with this one. It's like Korean fast food IMO.
