I'm meeting a friend and her 6 month old baby in London for a day out and trying to find a suitable restaurant to book for the three of us to have lunch. We will mainly be around the very centre e.g Soho, Covent Garden areas, as will be visiting the National Gallery. Does anyone have a recommendation? I would so appreciate suggestions as have never had to think about places suitable for when with a baby before. I guess ideally I wouldn't want it to be anywhere too busy or cramped, and with friendly staff who will be accommodating. Thanks in advance!
