Never had a bad meal at the Clog but it is too boring for me (the menu). I like the choice of things cooked with chilli, soy, ginger and so on. The O&O has a well balanced menu for that.
Still think my favourite restaurant round Lancashire is Cafe Grand and the Grand Hotel, Lytham.
On another note, i do fully TRUST the O&O, C&B and Millstone to serve me freshly prepared food. Sometimes i just don't trust it to be fresh at other local establishments. For example " Breaded King Prawns with a Chilli Sauce" - that could quite easily be purchased wholesale (ready prepared) and you get charged £7 for it.
