I hope this place has had a change of management. But our experience years ago was so horrible that it deserves resonance on YELP.com.
We were a group of 6 guys that reserved a dinner @ 6:30. When I had arrived early @ 6, they were ok with sitting me down to wait. Some middle-aged Asian lady (who I assumed was either the owner or manager based on her authoritative look) took one look at me and must've judged that based on my appearance I was up to no good. So she sent her lackey waiter to inform me that the all you can eat time officially began the moment I sat down. No problem. When my friends had arrived we began to order our food via checklist menu. We ordered what we thought would be enough for one round. It took one hour for the food to come out and once they brought a second sheet for us to order again, we had only received a third of the food we thought we had requested. So at the time, we thought it was logical to increase our orders so that they can bring the right proportion of food that we wanted. We waited for another half hour and the waiter only brings out two plates of teriyaki chicken. Another 5 minutes passes by and he informs us that the kitchen is closing and our all you can eat time is up. We are usually a passive group and even in situations where we didn't enjoy the food we ordered we often accepted the meal and only passively resolved to never come back. But this place BARELY served us food over the course of two hours. We didn't ask for slow-roasted stew, we asked for quick meals such as sushi. In fact the meat we received for BBQ was raw so what was the half-hour to one hour holdup for?
So by the time the waiter decided to come back and ask "any dessert?", 6 hungry guys let him have it. Only through the mid-point of the argument did we realize he was only the messenger and our angry stares were met by the sneaky manager who didn't seem to care. I assume that she assumed we were a bunch of mangy college students out to rape and pillage her place (why on earth would you have an all you can eat place across from SAIT anyways?), but we were working class professionals willing to pay for the service and food we received. Again this was an assumption, but see how it made and ass out her and me? That made no sense but it's been 3 years and I'm still pissed as shit about this incident.
Point being: DON'T offer an all-you-can eat service if you don't have the capacity to support customer requests.
