They share their menu which means we get to order from either places. The Mexican-Korean food takes longer time to prepare though.
Runs as a drinking bar by night, it tranforms itself into a Korean brunch & dessert cafe by the day.

Personally, would recommend sitting at Chicken up if you prefer a proper dining area and more conducive to chit chat. However, if you opt for some after-work drinks or party celebration, the hip music from the DTMM bar will work fly.
