SEPIA – SYDNEY – It’s the little things that count here. Take the salmon ball presented as an amuse-bouche: bite into it and a filling of smoked salmon roe provokes tantalising shock-waves of intense flavour. This is what chef Martin Benn does best: create seemingly simple dishes that astonish with their complexity, combining French techniques with Japanese ingredients such as dashi jelly, wakami oil and sobacha. Spanner-crab meat is teamed with sake-vinegar jelly, pea and horseradish and folded as carefully as origami; a simple curl of squid, decorated with miso-cured egg yolk and a wasabi flower, calls to mind the curves of a Miro painting.

And Benn’s nine-course menus end as strongly as they begin, with puddings such as The Pearl, a pristine sphere of white chocolate and finger lime.

KEENS STEAKHOUSE, NEW YORK – Keens serves fantastic steak but became famous for its even more fantastic mutton. It opened in 1885 and in 1935 served its millionth mutton chop. Somebody played a fanfare on a bugle that had supposedly been used in the War of the Roses. The manager gave a speech and waived the bill. The great shepherd in the sky alone knows how many mutton chops Keens has sold since then. A flock of a lot. Even without the fanfare and the speech, and even if you have to pay the bill, a Keens mutton chop remains one of the glories of Midtown Manhattan. Look out for the 50,000 long-stemmed clay pipes that hang, with a peculiar elegance, from the ceiling – not that you’re likely to miss them. Lillie Langtry, JP Morgan, Teddy Roosevelt and Babe Ruth ate here. You should too.

THE WHITE ROOM, AMSTERDAM – Arctic-white walls exuberantly encrusted with gold give this venerable 19th-century building its name. There the history stops. A recent revamp has introduced funky spherical chandeliers, a classy-yet-cool tone and an invigoratingly fresh take on the food. Chef Jacob Jan Boerma is guided by three culinary fundaments – ‘citrus, spice and vegetables’ – and his dishes are delicate, full of secrets and liable to mini explosions of surprising flavours. A slice of lime gives prawn tartare a zing as it slips onto your tongue; an intense zap of lemon lurks beneath a perfectly cooked piece of trout, with green-mustard sabayon. Wasabi, curry, Indonesian spices all play cameo roles. Each plate is feat of beauty, with bold colours, odd shapes and energetic composition.

INDIAN ACCENT, NEW DELHI – India’s restaurant critics are notoriously picky, which makes the non-stop gushing that has flowed since chef Manish Mehrotra’s opened here in2009 so significant. His genius lies in splicing global ingredients into regional recipes from India’s 29 states. So the stuffing he uses in the traditional kulcha – one of the country’s 400-plus breads – is chilli hoisin duck, or applewood-smoked bacon, or wild mushrooms and truffle oil. Kofta, the delicately spiced Indian dumpling, is made herewith tofu instead of paneer and served with a wok-tossed quinoa pulao. The result is not so much fusion as synergy: inventive twists that serve to accentuate the complex flavours of Indian food, and reason enough to plan a trip to the Indian capital.

EL MERCADO, LIMA – Lima’s culinary boom may have produced fancier restaurants but none, surely, is better loved than El Mercado, the casual lunch-only affair opened in 2010 by superstar local chef Rafael Osterling. Tucked away down a Miraflores side street, the permanently packed, semi-open-air space has the informal clatter and hum of an actual market with bartenders serving superb Pisco Sours to the endlessly replenished queue. As well as a full range of top-grade ceviches, the menu also includes excellent tiraditos such as the Nikkei (yellowfin tuna sliced thin, marinated in lime and served with sesame oil and avocado aioli). Other highlights include a superlative shrimp burger and the causa original, Osterling’s upmarket take on the Peruvian staple of mashed potato terrine layered with seafood.
