Well, evening service includes 5 hot dishes ( things like salmon, ribs, burgers, meatballs, various Thai dishes), some hot vegetarian things, a chef station preparing one dish ( eg, Peking duck, wonton soup, ), breads, cheeses, cold appetisers like sushi, hummus, small dishes, fruits, a selection of cakes pastries. It is extensive.
Breakfast now has an option of ordering eggs ( in the past this was the weak spot, offering only rather slimy looking scrambled eggs).
Service is very good.
Alcohol flows freely, including cocktails.
If there is a better lounge in Bangkok I’m yet to visit it ( it’s at least on a par with the Grand Hyatt). I simply can’t imagine being disappointed by it.
