Hi, some friends from NYC are in town next weekend. They are adventurous, appreciative eaters, but they are bringing their toddler. Any recs for places relatively central that are good, reasonable, and friendly towards young kids. I've seen plenty of recs for 'child friendly' places, but as I don't have kids, I imagine you can take a well behaved 9 year old to a certain places that a toddler wouldnt be as welcome or vice versa. They are staying in Knightsbridge.
