One of the most eagerly anticipated launches of the year, Neptune brings a new destination eatery to Russell Square. Located within the snazzy surroundings of recently opened The Principal London hotel, Neptune is the second restaurant from duo Brett Redman and Margaret Crow, and, with a gorgeous design by Russell Sage Studio, marks a chi chi step-up from their cult Hackney hangout The Richmond. Don’t be fooled by the glamorous surroundings, however — this restaurant is agreeably relaxed. As the name suggests, Neptune is heavily fish focused, a theme that leaves its mark on everything from a gleaming central oyster bar to cocktails specially designed to drink with shellfish. Kick off proceedings with Exmoor caviar, an absolute revelation with warm, soft waffles and cultured jersey cream, along with a platter of oysters on ice — ideally paired with a crisp Neptune martini. Be warned: enormous seafood platters cause quite a stir when brought to the table.
