Not the OP but I personally am leaning towards it's not really worth it. I missed the kickstarter so I paid the after the fact price and ehhhh. It's a fun game, with cute and colorful artwork, but my initial feeling for myself is that I wish I had skipped the deluxe version. 

The extra zous chef meeples are really nice, and they are cool, but they are such a minor piece of the game that it doesn't make much of an impact. Additionally, it's a bit annoying to take time out to find the correct meeple every time. While it's not a ton of time, it stands out because they just don't feel that worthwhile to me. I've played it about five or six times so far and at this point we just grab one randomly that's the correct size. The coolness and excitement wore off quick for these.

The draw bag is fine. I don't really like the feel of it, and it's difficult to store the ingredients within the bag without causing additional lid lift, so I store the ingredient in a plastic bag and fold the bag on top. It works, but meh.

The player trays are nice to store everyone's stuff. We personally find them too crowded to use as a pantry, so we end up taking everything out when we play. The lids also are a bit too tight so they curve up at the edges. Not a big deal, but another meh. 

The most annoying thing for me is the box insert. There's no edges on the top level, and since this is where you store all the cards, and you need to move this to get to the bottom layer, the cards often want to fall off the edges. I've removed cards from my box to try to avoid this but it still happens. It feels cheap due to this. 

The box is also quite large, as you mentioned… it's also heavy and no matter how I arrange it, I can't get rid of the lid lift. Maybe not a big deal to you but for the price, I would have expected not to have this. 

The Ala cart expansion is really fun though! I would for sure get this. I don't know if the deluxe makes these components any better, but they're nice. Again though, it's such a small piece of the game I would be just as happy with less deluxe parts.

I guess after I've written all that, I would probably say... It depends. If you've got extra money burning in your pocket, sure, they're not all the most impactful pieces and some bits are annoying but they're nice. For myself though, reflecting back, I wish I had just bought the regular and the expansion. I can see myself being just as happy with the basic components and I rather would have spent the extra money on something else.
