OGB is a speakeasy-style bar and restaurant inside the Old Government Building on Cathedral Square, Christchurch. The website describes a dimly lit, opulent cocktail bar in one of the city's most beautiful heritage buildings, with an extensive wine and beer list. Beer-battered fish and chips are on the menu at $28, as at 2026, along with steak frites, focaccia and a tasting platter. Food is served until 10pm, and late-night dishes are available until 1am. The website says the venue is dog friendly, with dog beer and water bowls.
Live music is on every weekend, the website says. Parlour, the room for private functions, can be hired for events. Nearby, the Godley Statue, 0.2 km away, is rated lower, from 31 reviews. Our pick in Cathedral Square for a late cocktail in a heritage building.
