Recruiting dinner (expensed)

I'm taking a potential senior employee out for dinner at the expense of the company. The candidate (victim?) is visiting from London and there will be six of us (2 couples + 2 kids, girls, 10) for dinner. I thought of 11 Madison but it's all booked up. Any recommendations, it's been a while since I've had someone else pay for dinner so something nice that would be interesting to a Londoner but is also suitable for 10 year old girls would be wonderful.
