Here are some words you never expected to read: Greggs champagne bar. But the no-frills baker’s latest marketing stunt is a pop-up bar where its famous bakes will be served with £75-a-glass champagne in bespoke sausage roll-etched coupes.

The “reservation-only” Greggs champagne bar, which claims to be “inspired by 1920s Paris wine bars”, opens next week in the Newcastle branch of Fenwick. The Christmas pop-up in the department store’s food hall seats 16 customers around a curved bar, with guests encouraged to ring vintage crystal bells for a refill of Louis Roederer Cristal, which costs £425 a bottle.

Greggs, which is headquartered in Newcastle, said its first-ever champagne bar paired its “iconic savoury menu of bakes and rolls” with handpicked bubbles served by the glass or bottle from famous names such as Bollinger and Laurent Perrier. It claims to be the only place in the area offering the exclusive champagne menu “by the glass”.

Mercifully, the food is cheaper at under £5 for a main. In keeping with Greggs’ affordable ethos, there are cheaper bubbles to pair with a cheese and onion bake, such as a £10 glass of Ca di Alte prosecco or an £11 “pink jammie fizz” – a prosecco-based cocktail inspired by Greggs’ jam doughnuts.
