THE week's best value offer has to be the endless glasses of soft drinks and canned fruit juices at the Coffee Shop in Omni The Hong Kong Hotel. Pay $29 and you can order unlimited litres of as many different drinks as you like. The catch is you have to order the buffet. Lunch buffet ($115) is from noon to 2.30 pm; the dinner spread ($210-$235) is on from 6.30 pm-10.30 pm.
