My son (19months) and daughter (4) love DJ's Jungle Adventure! It is well laid out and not as big as other soft play places (and it never seems to get too busy!!) The addition of mornings with activities is lovely so if you are stuck for something to do you can drop in for a play and sing!!!
The food choices are good and tasty!
I'd also highly recommend their private hire from 6.30-8.30....great for a pyjama party!!!
