If I have a chance, I’d like to admire the city from a height whenever I go to other country. Therefore, I don’t want to miss this chance when I visiting London. There are some ways that you can do this, the first choice id you can dining in a fine restaurant and enjoying the beautiful; the second is spend some money to climb the church’s top floor to see the city view. But if your trip is the save money line, which just like me, then you definitely cannot miss it.
