Greensmiths in Lower Marsh was crowded within minutes of opening its doors on Saturday morning.
The new locally-owned food shop on the corner of Frazier Street was holding a preview day for residents in advance of the official opening on Monday.
Greensmiths brings together a butcher, baker, greengrocer, coffee specialist and wine merchant under one roof.
The Ginger Pig, which will be familiar to Borough Market shoppers, filled one window with sausages. At the back of the shop The Old Post Office Bakery from Clapham had a display of bread and cakes.
It is expected that the rest of the three floor shop will open in a week's time.
Solstice, founded by chef Philip Britten who sources most of the friut and vegetables, will be the greengrocer in the basement. Waterloo Wines from Lant Street will also have a presence and a mezzanine will house a coffee shop.
The corner store, which had an open front and has been empty for some time, was last occupied by men's clothing shop Cohen's.
