Business Class Seat: on a few services pending on train type, such as the CRH380AL or CRH380BL trains. 3 seats per row (2+1). Lie-flat seats with airline style catering provided.
They are just like first-class on an airplane. The carriages are spacious with two meters (6.6 feet) of space between two rows. There are three seats in a row - two on one side and one on the other side of the aisle.
Oddly, business class is the top class of service though one might be inclined to think that first class is similar to an airplane (though attendants don't dote on you in the same manner as in business class on an airplane).
The sofa-like leather seats are comfortable. Unfold the sofa, and a man over 180cm (about 6 feet) can lie comfortably on it. The sofas are equipped with complete facilities. A mini LED TV set with many movies is folded in the left arm of each seat, and there is a power outlet under each seat.
The other reason why these seats are awesome is that there's plenty of room for our gazillion bags. If your budget permits business class, definitely do it. There's no question you'll be glad you did, especially on a long journey.
Our G train seats were in row 1 and quite far apart from each other though they are supposedly the sightseeing seats with huge windows and the ability to lie flat.
Upon being seated during both journeys we were presented a choice of bottled water or orange juice and a nice box of Chinese cookies.
Lunch was offered on our Beijing trip and our choices were seafood and duck. I declined because we had our lunch from the hotel.
