I really like the large one at the very start as long as the image is beautiful. Sometimes large images of food don't work. It's a tricky thing to get right. The food can look dull and colorless. Bright crisp food on white dishes that are well lit look best.
You have to be very careful about placement so that you make sure the photo does not cover the area above the fold. Google want that space for advertisers, and if you block it with a photo, you could have problems.
