It is located at Belfast Furniture Mall, the former home of Fulton's fine furnishings company, which is part of Balmoral Plaza.Yellow Door has acquired the former restaurant area of the 60,000 sq ft premises and will be serving up California-style dining to customers, which focuses on sharing plates and family-style dining.Andrew Dougan, a director of the business, said that one of the keys to the company's success lies in a firm ethos of using quality Northern Ireland produce."We have many outstanding producers here, whom we are proud to promote. Yellow Door aims to be at the heart of the community with a strong farm-to-table focus, and an emphasis on exceptionally flavoursome, seasonal food, cooked and presented in a variety of exciting dishes to match today's evolving palettes."Like everyone else, our business suffered during the recession, with the corporate catering side of the operation plunging by 80% as clients had to tighten their belts. But we always had faith in the Yellow Door brand and not only managed to keep going and absorb the loss, but even expanded the company during that time."He continued: "With the current upturn in the economy, we have now regained most of the ground we lost and 2014 should see our corporate catering business spring back up to pre-recession levels, as companies start to re-engage more with their customers."The wedding catering business has always maintained a steady demand and volume and this year we're looking at a 10% growth."Created by County Armagh chef Simon Dougan over 20 years ago, Yellow Door is well known for its deli outlets in Portadown, Lisburn, Belfast's Lisburn Road as well as a restaurant at the Ulster Museum and its catering division.Yellow Door is also the exclusive corporate caterer for Ulster Rugby at Ravenhill Rugby Club."We deliver fresh bread daily to customers in Belfast and Dublin and recently won a contract with the potential to produce in excess of half a million bread items and tray bakes annually for a company supplying Dublin airport and hospitals," Andrew added.The firm employs close to 150 people in full and part time positions, with an expected annual turnover this year of £5m.
