[1] Around the 1920s, Cesar Lacson Locsin and his sisters, Julianita "Nitang" Locsin-Gamboa included, started baking breads and cookies in their lone brick oven within the confines of their two-storey home.

[2][3] During the glory days of Silay, El Ideal served to cater to the gastronomic needs of gamblers who were often glued to their favorite pastime.

Locsin-Villanueva developed El Ideal by installing another brick oven, adding a restaurant that occupied the whole ground floor of the ancestral house, and expanding its product line that included refreshments.

In 1977, there was a move to widen Rizal St., which would mean taking down heritage structures, such as the Cesar Lacson Locsin Ancestral House.

[2] The Cesar Lacson Locsin Ancestral House is now protected from such threats through its stature as a heritage structure through a declaration by the National Historical Institute pursuant to board resolution no.
