I have reservations this Friday at both Ko and EMP to treat my girlfriend for her birthday. Much as I'd like to use both, my wallet and stomach can tackle only one. Whichever restaurant we choose, we'll be ordering the tasting menu (gourmand at EMP), not that this is an option at Ko.
I know EMP is the more "special" place with superior service, but we've already eaten the gourmand menu once there (a while back, though still after Humm took over the kitchen) and a Ko reservation is much harder to come by (at least it sure was for me), so I'd hate to miss my opportunity here.
We're leaning towards Ko, simply to try something new (we like Ssam a lot; split verdict on Milk Bar), but I'd be interested in hearing the opinions of other members who have eaten at both. My girlfriend and I both appreciate good service, but weight the food itself higher when choosing a restaurant - do the innovative flavors and techniques at Ko make it a worthy alternative to EMP's all-around excellence or will we leave Ko wishing we had stuck with the tried and true?
