Me & my partner are also interested in GCW and we went for a wedding dinner at GCW recently. Just my 2 cents worth on my experience there..
They had 2 screens in the Grand Ballroom, which meant that guests sitting in the wrong direction didn't have to strain their necks. We could all watch the videos comfortably from where we were. Plus point!
The garden backdrop was also beautiful. I love nature scenaries!
Though the curtains opened rather late.. somewhere half way into the dinner.
However, I had a few encounters with the waitress serving my table.?
At the start of the meal, she approached me after the first dish to inform me that they did not have cut chilli. Thing is, I didn't ask for it? in the first place. She probably got me mixed up with someone else!?
Somewhere into the middle of the dinner, there was a dish served that had sea cucumber, mushrooms and broccoli. I understand that these waitresses are mostly part time. So probably they weren't briefed on the quantity to serve each guest. Anyways, the waitress at my table started off by giving each person either 2 sea cucumbers and mushroom or vice versa. In the end, there weren't enough to go around cos each person was supposed to get one each. She then performed the "disappearing act", leaving the half served dish, serving spoon and unfilled plates on the table, and only re-appeared when the next dish was to be served.
I also find it a basic etiquette that if 2 people on the table are talking, you shouldn't go in between them, just to put the dish on the table and serve. There are so many "holes" around ( ie between people who aren't talking to each other), that would be a better option!
In conclusion, I feel that GCW has provided a good setting and ambience for the perfect wedding. Its short-comings lies in service, which probably cannot be helped much since their waitresses are mostly part-timers. However, I feel they can improve through basic training. For example, before the dish goes out, they could round up all servers and inform them that for this dish, one person is supposed to get one piece of each.
Probably those who are going for the wedding show could help to feedback to the coordinators attending to you so that GCW can take note of these and provide a better experience to all furture soon-to-be couples.
Cheers!
