We went out to the Glasshouse for Sunday lunch with friends and loved this gourmet pub cum restaurant in New Malden. The atmosphere was relaxed and child-friendly. There was a garden in the back with lots of space for the kids to play. The menu was varied with lots of seasonal dishes like (apparently changing every week) and there were half portions for the little ones as well.
The service was prompt and friendly, and price-wise it was reasonable given the quality of the food (budget from £40 per head for a three course meal)
