Panzer's Delicatessen

Equal parts deli counter and grocery store, this Jewish delicatessen in St John's Wood brings together smoked salmon, bagels, challah and kosher staples alongside a grocery range running from fresh juices to kosher wine. It's a premium-priced spot with the reviews to back it up — 4.3 stars from more than 1,300 — and whether you dine in, take away or order delivery, the doors are open from 7am until 8pm every day of the week.
