Golden Buddha in Decatur is one of those neighborhood institutions that feels older than its neon sign and familiar storefront would suggest, the kind of place families bring newcomers to when they want a taste of local ritual and reliably large portions. Opened in the mid-1970s by Been Lee, Golden Buddha settled into its long-standing location on Clairmont Road and built a reputation for hearty, American-friendly Chinese fare served in a roomy, slightly retro dining room that still shows the patina of decades of repeat business.
