I've just been here once, and I wasn't super impressed. The only other time I've had Indonesian food was at a restaurant in another city, and the food was extremely flavorful and pretty spicy, so that's what I thought the food here would be like as well. Unfortunately, I found the food a bit on the bland/mild side.
I tried the curry tofu, which came over rice with a side of pickled carrots and cucumbers and some shrimp chips. The pickled veggies were really sweet, they almost had a relish flavor which I did not really care for. The shrimp chips were partly soggy, and I ate my meal pretty much immediately after getting it from the cart, so I was surprised at that. I really enjoyed the tofu they used, but the curry needed quite a bit more flavor. I thought it was tasty but mild and a bit too mellow. I might try a different dish from Kakilima another time, but I'm in no rush to go back.
