I agree with all of you above. However I think it's worth looking at the whole place (and the kitchen) first. How they treat their food shows how they treat their guests.
Cleanliness (in my experience) doesn't have to mean safe food here.

Unless you take samples to analyze before you eat, there is no telling. Maybe just ask them what the price is for digouyou and if they use it :)

What is of more concern is: are there flies in the kitchen, don't eat uncooked food, are the vegetables washed (they do use human manure for fertilizer, and you sure know how many different illnesses and diseases, stomach problems and so on people can have), how do they keep the meat/fish? If fresh (except day-freah at the butcher) if not kept in a fridge (unless dried beef), you'll usually get stomach problems.
Just a couple things to keep in mind... :)

Wish I could upload a picture here. A couple weeks ago at a restaurant they had a cow sitting out in the parking lot, relaxed, munching away on corn... Unaware he was about to meet his end... That's called fresh :)

I second tigertiger on the SPAM thing.
It's just too random for this forum and too incoherent.

I think it's decent for London. Not too low and not high.
London isn't cheap, but it depends if you have a small apartment or if you move there with a family. I think you can find places in your budget if you're by yourself. 6 Most important things: 1. check where the nearest tube/metro lines are if you need them for going to work. Check the area and how safe it is (google maps has street view). 3 Buy your food at Tesco. (Check if there is one nearby your apartment as that saves you a LOT of money if you cook yourself). 4: bring your own lunch to work and a snack for the way back. Lunches add up quickly and sandwiches are not cheap. Why a snack for the way back? In case you get delayed in traffic/tube. 5. Bring water in case you get stuck in traffic/tube (very very important). 6. Get an Oyster card (for overground district trains and metro, tube and bus)
Fine dining is very expensive usually. If you're young and just want a fun dinner with friends, then there are also places that suit that. Wetherspoons or Lloyd's have decent foods and combo events (drinks and food platters)
Just some suggestions :)

Lol, that would be a fun bar. Especially if they have a mosquito farm (like an ant farm where you can see them grow up. Customers can stick in their arm for 5 minutes to get a free drink. (Very much required after so much blood-loss).

PS: my dad had dengue twice. Once in Africa, once in Thailand. It hits you out of the blue after the incubation period (your body just shuts down). The Thailand strain was never determined, not even by laboratories and "special hospitals for the tropics". There is not much you or they can do if you have dengue.

PS: if you get a netbook or laptop, get one with an I processor.
If it runs windows 7, you need 3gb memory or more for photoshop and video editing.
Windows 8: no idea how intensive that is as it is also available for tablets.
