This is a two-bar venue, ground-floor and basement, in the spectacularly renovated and re-purposed Grade I listed St. Mark's church in Mayfair (see historic interest section) taken over by Mercato Metropolitano. The space is now split across four floors and joins the growing number of London "street-food and bars" outlets.

On the ground floor there are two bars on the far-end altar space along with street-food outlets and a grocery store selling seasonal produce. The altar bar uses 1,000 plus coloured bricks handmade by the German Kraft team using broken glasses from their Elephant & Castle site.

In the gallery there are more food outlets and up on the rooftop there is an outside terrace. The food and drink comes from all over the world and in keeping with current trends sustainability is a hot topic here; single-use plastic and industrial or highly processed products all banned.

Mercato beers are brought in from the Elephant & Castle site as the brewery kit that used to be here in Mayfair has been removed. There are three beers in the core range, Herbert Pale Ale, Heike Blonde (Helles Lager) and Edel Weiss (wheat beer), alongside seasonal and collaborations.

The converted church also houses two BeBeMe wine bars. Hours given are for Mercato.
