Private room at restaurant/pub with veg meal, hot drinks for group of 14

Hello,

Please can someone recommend a restaurant or a pub with a private room in the London Bridge / Waterloo / Victoria areas, very near to these stations. This is for a group of 3 children (around 10 years of age) and 11 adults and to hang out. Most of the group are vegetarian and non-drinkers, so looking for meals/finger food to cater to this and it would be great if the pub can provide tea/coffee as drinks of choice. Looking at approx. 4 hours in the room including the time it takes to eat. Any additional information will be gratefully received eg how much this could cost, how the payment works eg is there a separate charge for room hire, is there a minimum charge for drinks, etc.

Many thanks
