There's no SM in Nagtahan. Maybe what you're reffering to is SM Center Point in Sta. Mesa (Araneta Ave. cor. R.M. Magsaysay Blvd.). We also have a new supermarket located at the corner of Nagtahan & R.M. Magsaysay Blvd., its the Save More Supermarket (owned & operated by SM).
Mercury Nagtahan is just beside the overpass going to Legarda St. (Sulucan St. cor. R.M. Magsaysay Blvd.) fronting Save More Supermarket.
From Las Pinas City, if you have a car, pass through South Super Hiway & turn right to Quirino Ave. going straight to Nagtahan. After you descended from Nagtahan Bridge, you can now find Save More Supermarket at the corner.
