Operated by the city, the Senior Center is a hub of activity for San Mateo's 50-and-over residents. Built in 1990, the colonial-style structure offers a peaceful, airy and light-filled environment. The city website states, "On any given day at the Senior Center, there can be a dozen things happening from yoga classes to a history seminar, from bingo to billiards or mahjong. We even have chef prepared meals."
