I was there (Batik Keris Terminal 2D) the last time because i wanted to buy a drink. And at the end i also bought a nice sling bag with "Keris" brand :-D
Beside Batik Keris, Plaza Bali is worth a visit too for souvenirs.

I shopped at the Keris shop in both Pacific Place and at the airport. In both locations, the clothing is not well organized. Please consider organizing by size, for example. Prices are reasonable (about USD 30 per shirt) for foreign pricing, but for local pricing, this is quite high. Also, staff could be trained in more customer service, rather than talking with each other and not offering to help (esp at airport).

After spending 3 days in Jakarta without visiting a batik shop was delighted to find Batik Keris at the airport. It stocked a great variety of items for men, women and home. There was a fitting room where I could quickly try out the stuff i liked. The price was good. I felt maybe I am a captive purchaser since I am at the airport with no other shops to compare prices or design with but later on in Yogyakarta I found shops from the same chain and the quality and pricing compared very well with the multitude of other shops in the market. Its been a year now and the fabric has held up very well, the colors don't run and the stitching is as sturdy as new. I am very pleased with Batik Keris wares and highly recommend this business.
