The Lounge at Terminal C can get busy in the early afternoon hours with all the international flights, so lately I found myself just going to straight to the Air France lounge, which is fairly large in terms of size at Terminal E. I mostly took Mint flights to SFO/LAX, so the AF lounge is actually closer to C8/9/10 that most Mint flights use.
While the decor of the AF lounge is a bit sterile, they have a good range of alcoholic and non-alcoholic beverages, along with a good range of soups, sandwiches, salad, and hot dishes. In the afternoon hours when they mainly served Hainan Airlines' passengers, they have one hot Asian dish. They also have many cup noodles out. If you come during the evening hours, they will switch to some pasta dishes with a meat dish, along with a fancier cold cuts and cheese platter.
