1. Create brass rubbings

Instead of the conventional souvenirs one can get in London markets, brass rubbings are a great substitute, especially if tourists get to make it themselves.

Underneath St. Martin-in-the-Fields in Trafalgar Square lies a crypt where guests can craft their own figurines with the use of brass rubbings. The Brass Rubbing Center welcomes those who want to be a little creative and take something with them back home. They leave visitors with materials and instructions, which would cost from £4.50 up.

2. Dine in the dark

Dans le Noir may have started in Paris but it's already garnered a strong following of foodies out for an adventure. The restaurant serves customers in complete darkness and in turn, diners will eat their meals in the dark as well.

The restaurant aims to heighten the senses of taste and smell of the customers. If travelers and curious locals are up to an even greater challenge, Dans le Noir also has a blind tasting menu, which is a surprise menu.

3. Visit Platform 9 ¾

Harry Potter fans won't be disappointed if they ever choose to look for Platform 9 ¾ since it is a real space in actual train station in London. While it's not really located between platforms 9 and 10, it is positioned off to a side of King Cross Station.

4. Drink with Sherlock Holmes.

The Sherlock Holmes Pub is just like any exciting pubs in town but the décor is reminiscent of the world's most famous detective's time, with the upstairs area designed like Sherlock's study room.

Guests can literally drink with the detective, as its statue stands just in a corner of the room.
