A 1 year old is going to be loud though, not saying to leave him/her to it if they are genuinely being naughty. Ive taken my 1 year old daughter to restaurants with us and had nice meals, if shes loud and makes noises like normal babys do then so be it, im paying the same as everyone else to be there.
The last place we went to was Novikov in Mayfair, as posh as they come but not a single person had a problem with us having our daughter with us in a high chair. Saying that though she is pretty good 90% of the time and eats with us
