Constructive criticism can work in the favour of restaurant owners who choose to act in a positive way, i will always make my own mind up and never jump on the band wagon of one or two individuals, but might have a second thought if the majority of people air there views which are either very positive or very negative , lets face it we don't all like Marmite and i could never convince somebody that has tried it and hated it,that is nice,but if you have not tried it and you say it not nice because your friends, Nans, uncles, cousin, told you its not nice, then your opinion will count for nothing, there are lots of people on this forum i respect and i value there opinions and there are some people that just go out of there way,and join to discredit someones business you are the only one who can decide who you believe and what action you take, just don't be fooled by every thing you read ,!!!!
