+ Falafel burgers with chili sauce. Divine, best burger i've ever eaten.

- Take a number. What's wrong with the old fashioned queue in a line? With take a number you never know how long you'll have to wait as people take one, see it's far away and leave. So when your number is 30 away, there could be anywhere between 1 and 30 people before you.

+ White chocolate Lion bars. All chocolate bars should be these.

- Green man lights should mean it's safe to cross the road. Not that traffic could still appear any second.

+ Student discount. If you have a student card, whether you're still a student or not, ask for discount. Most places don't check it's valid. Some don't even ask to see the card so try even if you don't have one.

- Scaffolding/road works. Around every monument/statue/interesting building there seems to be some kind of building works spoiling it. Just give it a rest and be content with the world we have for a minute.
