Service in KL Bars, Restaurants, etc (Kuala Lumpur)

Many times we visit restaurants, bars, bistros and the like, many times with guests - be it private or business. The atmosphere, ambience and even the food are good, but the service spoils the experience. Please let me know where you had such encounters and we will try to improve the situation for the patrons as well as the establishment itself. Cheers and many thanks in advance. Alex Wittberger
