Ambience: It's a pretty small one compared to the others, but there's the brown line coming up right next to the CC, so it looks like there will be more crowds soon! Apart from that it was a relaxing location, without any crowds.
Service: I managed to win a Christmas voucher from burpple, so finally went there with my family. The stall when I went was run by two young guys, and we were amazed by their service and ability as they were both chefs as well! They gave many recommendations, and were really friendly.
Food: Grumpy bear's menu as always is humongous, with it's main speciality chicken being as always, amazing. However, the KBCC branch has additional baked rice/pasta as well as Bible tea from Par-tea available. The one I got was flavourful with surprising additions of mushroom and hard veggie, which broke away from the potential monotony. It was incredibly filling!
The meal was generally a decent one for it's price, but I believe that if I stayed nearer I may go more often.
