Tip 21: Sushi!

If you're working late, or have had after-work drinks, and you're after a healthy and cheap meal, head to Itsu.

They do half-price on everything in store half an hour before closing. Get a cheap Japanese feed; sushi, noodles, soups, salads.

Most stores close around 8-9pm. For a store near you and opening (or closing!) hours, visit http://www.itsu.com/locations/shops/ 

Tip 12: A View From The Top

At 308 meters and 72 floors high, The Shard gives an unrivaled view of London. Because of this, it may be tempting to visit the viewing platform. But here is a hack - save the £25 and visit the atrium bar on the 31st floor for free! You don't need to book, and you can nurse a £4.50 glass of wine for as long as you like and take in the view. It's open til 1am, and the dress code is a smart causal. For more info check out their website http://www.aquashard.co.uk/. 

Tip 20: Easy London

City mapper’s mission? Make cities easier to use.

This app is invaluable for finding your way around London and much better than an A-Z. Trust me. You select a destination and it gives you every option available to get there including real time tube and bus times and costs. A personal favourite is the taxi option - you can justify taking a cab if you compare it to the time and cost of public transport. Plus, it remembers your favourite/frequent destinations so it’s not such a big deal if typing in your home address is not possible at the time.

Genius.

Tip 19: Probably the Best Pizza in London

Saying something is the "best in London" is a big call - but these words came from someone who has lived in Naples (which probably does the best pizza in the world).

Where can I find this pizza? Franco Manca.

Where is Franco Manca? The restaurants are in Tottenham Court Road, Brixton, Chiswick, Northcote, Stratford Westfield, and Balham.

What do they serve? Pizza - and that's pretty much it. (But you can buy beer and wine)

What makes it so good? The sourdough base and the limited, yet delicious toppings which are then wood-fired to perfection. They are traditional, rustic Italian pizzas. There are only 6 on the menu, and usually one or two specials.

How much are they? Here's the good part - they are really cheap! Pizza breads start at £4.50, and the most expensive pizza is about £7.50. I can barely finish one.

Can I book? Nope, you have to turn up, line up and wait. 2 is the best number to go in. You may have to wait a while, but it is worth it!
