To be honest, mas mapadadali ang biyahe mo kung sasakay ka na lang ng tren mula sa MRT-3 Taft Avenue Station. Kapag kasi sumakay ka ng EDSA Carousel bus sa Pasay Rotonda (aka Taft Avenue–EDSA Intersection; also the place where the **LRT-1 EDSA and MRT-3 Taft Avenue Stations meet), sa Ortigas Bus Stop (beneath MRT-3 Ortigas Station) ka makabababa after Guadalupe. Then, you will have to walk towards Doña Julia Vargas Avenue in the middle of Ortigas Centre (located at the taxi bay just after passing by Concentrix and the bus bay sa SM Megamall) until you reach Meralco Avenue.

I recommend boarding the train na lang from MRT-3 Taft Avenue Station and detraining at MRT-3 Shaw Boulevard Station, since (1) mas malapit siya sa namesake niyang kalsada (i.e., Shaw Boulevard), (2) Shaw Boulevard is located on the southern side of Ortigas, and (3) as far as I know, may sakayan doon patungong Meralco Avenue, sa Greenfield District sa tapat ng Chowking, just across Shangri-La Plaza. Mayroon din sa Park Lea Jeepney Terminal, just across Starmall EDSA–Shaw sa kabilang side ng flyover (may Andok’s sa bungad).

Now, hindi ko na kabisado ang ruta ng mga jeep na ito since sinarado ang Meralco Avenue mula sa kanto ng Unimart hanggang sa Valle Verde Terraces daw due to the ongoing construction of the Metro Manila Subway, but ang maaari mo yatang sakyan ay iyong mga patungong Rizal (biyaheng Antipolo, Binangonan, Tanay, o Taytay). Alternatively, maaari ka ring sumakay ng patungong Pasig Palengke. However, it will just continue its course along Shaw Boulevard. Magpababa ka na lang sa Kapitolyo (tapat ng magkatabing Shell at Petron), cross the street to Unimart, and walk towards Meralco Avenue.
