Bubala restaurant review: ‘The carrots nearly made me take a Covid test'
My wedding reception was held upstairs at the Ivy. Back then, there was only one Ivy: our favourite spot in London, where — in the pre-soft-play days, when our disposable income wasn't funnelled directly into Bluey Inc — we'd had our favourite, joyous, boozy dinners. It was the only possible venue. But now, with an Ivy on every high street, it's like announcing we got married at a Zizzi. And here, with slight regret, I present another cautionary tale of overexpansion. I love Bubala. It opened in Spitalfields in 2019, offering a vibrant take on Middle Eastern food that was delicious, quietly vegetarian and deeply hip — not that I'm in any position to judge hipness, but various beard-oil users have assured me that it was. Its firstborn arrived in Soho a few years later, and this sequel proved even better. It was The Godfather Part II, Thor: Ragnarok, Miley Cyrus. Bubala 3 is a 15-minute trek from King's Cross station, located in the sprawling techtropolis, presumably to vary the lunch options for Google and Facebook employees. The walk gave me plenty of time to hype up the food to my husband, J. By the end of my pitch, he was practically jogging there. We were welcomed in by a brilliant Kiwi manager, but it's not quite the restaurant I know — it's cool and airy rather than cosy, all concrete, exposed plaster and towering arched windows. It would be hard to say the place had much personality, as if it's ready to be turned into a Wagamama or Côte at a moment's notice. Inside Bubala REBECCA HOPE You have the option of a £33 per person mezze sharing menu or choosing, as we did, from the twenty or so à la carte dishes. We picked about half of them. The falafels were 10/10. Just the right amount of give on the outside and fluff on the inside, all served on a tahini so white, smooth and creamy it should have an SPF number. Bread and hummus were also spot-on. The laffa, a scorched flatbread threatening to become a naan, tore with a sublime stretchiness and was the perfect mode of transport to shovel in the glossy hummus, pimped up with nutty burnt butter. 'See?' I said to J. But, alas, man cannot live on chickpeas alone. Charred halloumi was squidgy and succulent, the antithesis of the squeaky vulcanised rubber found at every barbecue. In Soho, it comes topped with a phenomenal chamomile honey. Here it's been punished with half a jar of marmalade. Sickly and dissonant, it tasted as though a label had been misread — even Paddington would have scraped off the stuff. The spanakopita looked fantastic — a chimera of the Greek staple with Turkish borek pastry — but was polystyrene dry; the fist of sesame-miso chutney on the side delicious but ultimately unable to perform CPR on its neighbour. Leeks came doused in a Mexican-themed gratinated béchamel of jalapeños and sheep's cheese, with a tangy amba (mango pickle, to save you a google) reminding us we've got one foot in the Middle East. But the leeks were unforgivably tough. The thoughtfully provided utility knife wasn't up to the job — I think I'd have needed a power tool. I will forgive them for calling hash brown cubes 'latkes', but I can't forgive them for the potato being grey. The carrot main was so underflavoured it could have been a side for a Sunday roast — I almost took a Covid test. The button mushrooms on the pickle plate were overly soft, slightly redolent of a Travelodge breakfast. The basbousa dessert, a warm semolina cake with pineapple and coconut, had intricate flavours but was stone cold in the middle. Unforced error after unforced error that made me keep apologising to J. Carrots, feta and apricot Maybe these were all teething problems — the restaurant has only been open a month. ('Ask your server about our daily wine specials!' screamed a box on the menu. I asked a server, who asked another server, who told us there were no wine specials.) Maybe we caught them on an off day. Or maybe this is a moment for Bubala to take a beat, hopefully before branches start to take hold across the country like knotweed. Or Ivy. ★★★☆☆ 1 Cadence Court, Lewis Cubitt Park, London N1; Charlotte Ivers is away

Warning to homeowners using ChatGPT for renovation advice
Householder should be cautious when following the AI bots DIY advice. Homeowners turning to ChatGPT for renovation advice have been warned that it could be a costly mistake. The number of people using the AI chatbot for decoration ideas and tips has soared, with Google searches for 'ChatGPT design my room' skyrocketing by 4,000% in just six months. The viral trend sees users uploading photos of their spaces and getting AI-powered makeover advice. Experts at MoneySuperMarket are urging homeowners to do their homework before they attempt to bring their AI visions to life - and avoid costly mistakes and the risk of voiding their home insurance. Following the surge in searches, Kara Gammell, insurance expert at MoneySuperMarket, is now warning homeowners of the complications that may arise if they fail to do your research. She said: "If you're planning significant home renovations such as knocking down walls, roofing, fitting a new bathroom or anything that requires approval or permission, it's vital to let your insurer know beforehand. Failing to disclose changes could impact your cover. "If you're planning on using AI for inspiration for your DIY home improvements, Kara suggests including information such as your budget, level of skill and building restrictions in as much detail as possible in the prompt you give the AI tool. "This will help you to get the most out of AI and make sure you receive realistic and safe suggestions for your home renovation plans. Follow Kara's savvy advice before carrying out any renovations Check your policy details Before diving into any DIY, check your home insurance is up to date and you're clear on what's covered. Knowing the ins and outs of your policy is key to making sure your handiwork doesn't accidentally void your cover. Even more comprehensive home insurance policies that include accidental damage might exclude cover for poor workmanship or faulty materials. So, a claim for damage caused by DIY work, or for tasks such as plumbing or electrical work you're not qualified for, may be denied. Join the Daily Record WhatsApp community!

Get clued up on what DIY work could affect your cover Before you pick up a hammer, it's crucial to know which DIY jobs could impact your insurance. Roof repairs - Fixing tiles or gutters might seem easy, but a DIY job gone wrong can cause leaks or even structural damage. Most insurers expect major roof work to be carried out by qualified professionals. Removing walls - Not checking if walls are load-bearing, or removing them without proper permission, could compromise the structure of the house - leading to potential safety hazards and extensive property damage. Plumbing work - Plumbing work, especially involving water supplies and drainage can lead to leaks or water damage if not done properly. Electrical work - DIY electrical work, like rewiring or adding sockets, can be risky and often falls short of safety standards. Faulty wiring is a major fire hazard and could void your insurance if it's not done correctly. Adding outbuildings - Adding a shed, summerhouse, or garden office might boost your space, but it could also impact your home's value and won't always be covered unless it's added to your policy. Make sure to update your buildings and contents insurance with your provider if you're thinking of adding one.
