re: We went to a vietnamese wedding last night and the food was incredible.

Most places serves the crab meat soup without the shark fins, its not a game breaker with/without the fins. Since its a Vietnamese, you are suppose to have a bottle of cognac on each table, but too bad Crystal Palace venues has banned this. FWIW, if you ever get invited to a wedding @panda king. The food there is better and there's no bottle ban.
