The most talked about restaurant for dinner dates is the Cafe Juanita which is located at 20 W Capitol Dr, Pasig, 1603. They serve menus close to Filipino home cooking such as pork adobo, angel-hair pasta with aligue (crab fat) sauce and deep-fried asohos, and laing. There's also Florabel Restaurant at the ground floor of the new Estancia Mall. It's owned by the well-known Chef Florabel herself.
