After hours of sweating it out in steam rooms and saunas, we want to re-tox with real grub, not itty-bitty cucumbers and carrot sticks. The restaurant inside Imperial Health Spa gets that, serving up remarkably satisfying Korean fare that would only stink up the lavender-scented air at frillier establishments. In the small, cafeteria-like setting, you'll find substantial dishes of kimchi fried rice, ddeokbokki (chewy rice cakes drenched in spicy red sauce), naengmyeon (buckwheat noodles in a cold, savory broth), kalguksu (handmade noodle soup) and miyeok guk (the same type of seaweed soup that Korean women slurp for nourishment after giving birth—a tough day at the spa is pretty much the same, right?), as well as with Korean shaved ice to cool you down after being incubated in the dungeonesque red-clay room. Now this is how we say, "Ahhhhh." $
