Simply Asia simply aweful

We have never received worse service in a restaurant. We arrived at 5.40 to enjoy the sushi special which ends at 6pm. We were told that there was a 30 to 40min waiting time. One hour later the manager appeared to check whether we were happy. She looked surprised to hear that we were hungry by now. 20mins later. No waittress. No food. No manager in sight. We found the manager at the front desk. When we complained about the 80min waiting time, her response was that this was the first she heard of this. Meanwhile, take away sushi was leaving the restaurant at a steady stream. 90 mins later our food arrived. The food was good. When we paid and left, the manager avoided eye contact and pretended to be busy under the counter. No apology. What a dissapointment!
