The clipper lounge isn't strictly CX. It's a 3rd party lounge shared by a bunch of carriers. It's facilities are pretty basic: drinks, food, magazines, places to sit. I don't think there's internet or shower facilities. But then again, I haven't been there in about 2 years. BA had a lounge in BOM that closed 2 years ago for renovations or something. If that one is open and you're at least MPC Gold you could probably use that instead.
