On Bethel Island in the Sacramento-San Joaquin Delta, the Rusty Porthole Bar and Grill is a beloved Delta institution: a genuine California waterway bar where houseboat dwellers, bass fishermen, and weekend boaters converge for cold beers, fresh Delta catfish and bass, and the lazy, sun-baked, distinctly Californian experience of drinking cold beer on a Delta waterway while watching the tule fog roll in. The Delta is California’s most overlooked waterway; the Rusty Porthole is its most honest bar.
