Boathouse Sushi ****roach fest

I went to boathouse Sushi this afternoon and was really impressed with the quality of the food. After sitting down for about 30 minutes I saw a ****roach against the wall walking around. I immediately lost my appetite and alerted the manager. He just walked over and killed and walked back over to me and said oh I killed it. I then just sat there stunned because then I realised that there were quite a few flies flying around as well. I then asked for the bill because we were not going to co tinue eating in a place that just thinks its ok for pests to be walking around. Upon leaving another one came out and was walking right next to where they are preparing the food and then I noticed that none of the people making the sushi were wearing gloves. I am sick to my stomach and appalled by the service received
