Time Out says
Though nominally themed around Argentina (the upstairs restaurant La Estancia is an Argentinian steakhouse), El Gardel is a sort of institutionalised celebration of all things Latino – musical, aesthetic and alcoholic. Vintage snaps of presumably famous salsa and tango dancers adorn the walls, while that same music drifts out of the sound system. El Gardel tends to attract an older crowd – many of them diners on their way back down from the restaurant – and indeed anyone who's sick of sipping their cocktails to a soundtrack of electro beats. Every Wednesday night is salsa night – so whether you’re experienced with the passionate dance or a novice just starting out, come down to wiggle those hips.
