The menu is divided into lots of small plates to start and larger dishes for mains, all of which are designed to be shared between the table. There’s fourteen different little snacks to try, some of which come as a single piece (the glazed chicken wing with caviar (£3), for example, is pretty hard to divide between more than one person, so you’re best ordering your own if you want to try it). They’re a masterclass in presentation – beautiful little taro dumplings stuffed with Taiwanese sausage (£5.25 for three), slithers of wobbly, delicate beef tendon served in a piquant chilli vinaigrette (£5.50) and jet-black cuttlefish toasts served with a thick, rich whipped cod’s roe (£5 for two). The highlights for us were a bowl of silky, jiggling steamed egg (£4.75), set in the bowl above a delicate truffle-infused broth, and the tomato and smoked eel (£5.25), which delicately balanced fresh, sweet, acidic tomatoes with the rich, smoky, umami-laden fish.
There’s also a little selection of bak kwa (£7), a sort of sweet Asian jerky eaten as a snack all over the continent, which comes served like a box of After Eights alongside little pots of beef fat mayonnaise, pickled radish and Sichuan relish. It’s certainly the nicest bak kwa we’ve ever had (although, to be honest, we’ve only had it once or twice in the past), so if it piques your interest it’s a must-order dish.
While the little starter plates are a way for the chefs at Xu to show off their skills and bring diners a flurry of different flavours and textures, we felt the main courses offered the truest taste of Taiwanese cuisine. If there’s one dish to order, it’s the chilli egg drop crab (£14.50), a bright orange mound of white and brown crab meat swimming in a rich egg sauce with fistfuls of garlic, fermented shrimp and ear-ringing chilli. The char siu Iberico pork collar (£18.50) comes in a sweet, beautifully charred marinade, while a big bowl of shou pa chicken (£18.50) is moist, covered in refreshing ginger and spring onion and comes with a seriously addictive white pepper and chicken skin dipping salt. If you like your beef aged and, well, incredibly beefy, the black pepper beef rump cap (£15) is beautiful, full of flavour and comes with a big rich fried egg.
