Abacus is so smart and cool and welcoming and relaxed you'll wonder what you ever did before you discovered it. The ambience is smart casual and, with three bars and a club over three floors, there's lots of room for either calm dining or wild nights.
Think mood-enhancing lighting, leather cubes and seating, chic mirrors and sleek stylishness, a perfect backdrop for you and your date or friends to spend a great evening. The menu features both nibbly bits, which perfectly complement the enormous drinks list, and proper international dishes for sit-down meals.
Try the fish finger sandwich with chunky chips, or do the three-course thing: small plate of seared beef skewers with toasted sesame seeds and oyster sauce, big plate of char-grilled swordfish with rocket salad, and pud of classic lemon tart. Then dance the night away.
