"Ao-Chan is a Japanese style BBQ meat specialty store founded in 1995 located on the second floor of Concorde Hotel, Orchard Road. Comfortable and service oriented, Ao-Chan offers the atmosphere of a Japanese grill and roast meat shop which offers a taste of the good old Japanese yakiniku abroad.
The secret homemade Tare dipping sauce brings out the best in meat, basking it in exquisite flavour. Only meat with the finest quality is served here, the distinct marbling on the beef is testament to the excellent standard.
While the weekday crowd consist of businessmen, the atmosphere transforms during the weekend entertaining customers of all ages. There are also private dining rooms, ideal for entertaining special guests and hosting small events. A phone reservation is the only way to avoid disappointment should you want to drop by to visit them." -- translated and taken off their website.
Ao-Chan caters mainly to the Japanese expat community and does not need to do any additional advertisement to keep their business afloat. Their clientele is built-up largely via word-of-mouth and is a hidden secret gem of a place.
