It's not fancy but I wouldn't say it sucks. Unless it was all home made and the person making it didn't know how to cook.Food sux in Lao wedding, it's so cheap compared to Cambodian or Thai. We get the same sticky rice, dried meat, larb, nam, etc. Then you get the usual drunk crowd who always gets plastered and either embarrasses people or pick fights. Going once is enough, more than that and you want to hang yourself. Yea, I'm Lao.
Lao and Thai food, in case you didn't know, are very similar. Southeast Asian food in general have several similar dishes.
I've never seen stick rice served at a Lao wedding before, that's interesting. Actually, now that I think of it I've never seen any of the stuff you mentioned at any of the weddings I've been too. I mean there was Lao food there but it wasn't everyday stuff like that, they at least had some quality stuff.
