I have to comment about MSG. In the US, studies have found it to cause cancer in lab studies. I mean - big studies - it is a confirmed fact!!! The big push there is to privide food without it. I am very alarmed to see in the UK people dont care about that or just dont know about it. I always read all the packages and make sure that nothing i buy has MSG in it!! I ate at one chinese place here and after eating, had terrible symptoms - dizziness, giddiness and just felt terrible - symptoms from too much MSG!! I will not have any type of chinese food in the Uk anymore because none of them say their food is MSG free - in the US, all the restaurants advertise that they are 100% MSG free.
This 'msg' is found in Walkers Crisps and Pringles and infact most food snacks, its also under the name of Flavour Enhancer or E621, have a look at the back of a packet of crisps next time you have some.
On that note though, i've too had a head ache after eating at ?5 eat all you can type of place, and it is due to the amount of msg they use, but this can be overcome by drinking lots of fluids (not alchohol). So if any of you are thinking of going to a chinese buffet then try to look for places that advertise 'msg free' or just drink loads(water).
