I went last year and had a lot of fun. With that being said it really is a"go go once and done" type of event IMO. There is an incredible amount of pig parts all around so be prepared for it. Not much veggies. Some very good cheeses from importers. Excellent wines.
VIP is not worth the cost since you are going to pig out anyway, if you will pardon the pun. But if you want to know all there is to know etc.. go for it.
As you may know-5 pigs (different breeds), five chefs. Make sure you stop at the table to taste the 5 different roast pork all prepared the same and taste the differences.
