Many restaurants in the Philippines provide discounts for senior citizens as mandated by RA 9994. Popular chains like Jollibee, McDonald's, and Mang Inasal often offer 20% off on food and beverages for seniors. Additionally, local eateries and some grocery stores might also participate in this discount scheme. It's best to check with individual restaurants for their specific policies, as some may have different terms or additional offers. For the latest information, visiting the official websites or contacting the restaurants directly can provide clarity.
