Large restaurant chains have invaded the city centre of Helsinki. They are taken over many of the places considered advantageous for commerce. Competition for the best commercial real estate has markedly increased. The increase in restaurant chains can be seen best in hotel and staff restaurants and pubs. The greatest demand is for locations in downtown Helsinki, specifically in the 00100 postal code area, which is the most expensive area for businesses. The price of business premises has skyrocketed in recent years. One reason for the price rise is that the City of Helsinki has begun to encourage competition in the leasing of its real estate. Some of the large chains started to divide their restaurants into separate sections. They try to get several consumer groups under one roof by offering something for everyone. The restaurant of a large business is still not always successful.
