Food yes, bars no.
Public bar is no place for a child at all. Strictly over 18's only. Sunday lunches, daytime dining yes I would be all for it in a respectable place and in a designated dining area. Bars are no places for children due to what they may witness or hear or be involved in, and what kind of parent or adult would want their child in such an environment anyway? UK bars are generally in a decline anyway, lets face it as the supermarkets have cleaned up in off sales, but many bars are still a place for high intake high -volume, vertical binge drinking, and therefore fighting, swearing, drunkenness, drug exchanging, stolen goods swopping, shootings and stabbings are generally to be expected and witnessed at some time or other. Least they are around my way in most of the rougher places - its no place for a child. Keep them out!!
