I went from Hong Kong to Mumbai, but I remember them announcing for passengers going onwards to Dubai, they had to remain on board. The Clipper Lounge in Mumbai is definitely no Wing/Pier, but for a 3rd party lounge that caters to many airlines, I actually found the service quite nice. The food was actually quite good; samosas, salads, fresh sandwiches, and lots of drinks, though limited on the alcohol. Only problem is that it is a 3rd party lounge and therefore gets very crowded.
