I went by to Kala Ghoda Cafe last week. First off, the place is small, but you have to appreciate how they have decorated the interiors despite the handicap of space. The ambience is really nice, similar to studio cafe's you may visit in other cities around the world. However, the service was appalling; there were just two waiters, and even they were taking their own sweet time to respond. One of them even waited to finish his conversation on the phone before coming to our table.
Secondly, and this is the crux of the matter, they serve me an Iced Tea (which wasn't so good) along with a sugar syrup dispenser with ANTS walking all over it! Second item, a toast with cheese that was surprisingly closer to garlic bread with cheese than a simple toast.
Visit KGC if you want to experience a nice ambience and possible share a cup of tea/coffee (hopefully better than the iced tea), but not for anything else.
