we are meeting family from Birmingham in Windsor as it's half way for both of us. Forecast doesnt look great. We have (thanks to Mumsnet) for the last two years met up in Saville Gardens and enjoyed super picnic. Now I am thinking we might need to have a back up plan. There will be 7 adults, DS1 who's 8, DS2 nearly 3 plus a new born. Bearing in mind it's also Father's day, has anyone any recommendations for an easy/plain lunch and not too pricey (our Christmas meal was over £300)? Preferably with some outside space in case the weather cheers up. Thanks!
