Riverview Restaurant at 20 Estes Street in Ipswich, Massachusetts, is an unassuming, cash-only local institution operating inside a retro 1950s-to-1960s time capsule. Famous exclusively for serving uniquely delicious, personal-sized thin-crust bar pizzas on wax paper rather than traditional plates, it offers a nostalgic, no-frills dining experience complete with red booths and a classic jukebox.
