It appears that tickets went on sale yesterday but the menus haven’t been released yet. I've been twice before and enjoyed it. One year, unfortunately, the weather drove the event indoors to their convention space and that I did not enjoy as much. When outdoors, it's very fun. Food was great. LOTS of wine - but it's small pours in my recollection. Very nice to not have to pay at each "booth" as you do at Disney. I have seen kids but the event definitely has more of an adult cocktail party feel - particularly as the evening progresses.
They've always released the menus - the two nights have historically differed a bit in food offerings - well in advance. I'm surprised they haven't already and almost wondering if the purchase tickets button wasn't supposed to go live just yet as their front page still says "coming soon." I would wait and look at the menu, which I'd expect will be out soon. The dishes I remember were not vegetarian (steak, fried chicken, duck, sliders) but that doesn't mean there aren't veg items. On the menu tab you can click through and see some of the dishes from prior years.
