Informal email Hi juan, It was great to hear from you again, Glad to hear that you and your sister are coming to visit London next weekend, I thought  you might be interested to know a little bit of my city before you come. The first place you should visit is Westminster you'll see the house of parliaments of London which is an amazing building where you can find the famous big Ben, from there you could walk up to London eye which is a high-rice noria so that you can see the city from the highs and take stunning photos. In London you can find food from many places like Poland, Indian, Chinese, Colombian, Etc there are street markets like camden town, brixton market, where you could combine shopping with food, I really recommend you fish and chips which is a typical British dish. Maybe you could be interested in museums most of them are free like The British museum, natural history museum, national gallery of London, science museum, saatch gallery that is located in one of the most affluent paces in London. And of course you can't leave London without visiting my house where you can have a nice cup of tea. Anyway, I must go and get on with my work! Say hello to your family. Take care, Carlos.
