1. You could get together with the other "legit" owners and lobby the Councillors to take action.
2. You could get together with the other owners and seek the advice of a planning consultant. An initial (probably free of charge) meeting would give you an idea on how to proceed or if you had a worthwhile case. Bring the information you've gathered including copies of the planning permissions of the prime suspects.
3. You could continue to gather evidence yourself in support of your case, submit it to the LA and wait for Planning Enforcement to do it's job.
It's already been said that there's a grey area between a primary permitted use an an acceptable subsidiary use. Each case is different. How do you expect anyone on a forum to make a definitive judgement on whether or not somebody's complying with a permission or not, without knowing all the details and specific wordings of the legal document- the Planning Permission? It's not possible.
You've mentioned 5 different type of businesses - restaurants, take-aways, shops, cafe bars and even "restaurant-take-aways", some of whom advertise their take-away service, some who don't.
You seem to be certain that very few operate in compliance with their planning permission. If you submit the evidence that proves this, then you will be highly likely to get the result you want. On the other hand, if you dont get the required result, well then it may be that the suspects were indeed complying and abiding with the Planning laws.
