Breakfast would have been different if Maya Grill still did buffet but as I am in mourning about this then our two favourites would be
Crystal Palace, - love the buffet, plenty of fruit choice for DD, DS loves the pastries there and I love the omelet station. Character interaction is great and always had fantastic service.
CRT - not the best meal at WDW for food but love the photo with Cinderella and eating in the castle is amazing. As a family we adore this one.
Dinner Boma- since our 2007 trip this was our favourite and a must-do. DD tells me the prime rib is her favourite and they always have great fruit. DH and I love the variety of salads. The hummous is outstanding. Puddings are a big hit with all of us. Picky DD loves the fact that you can 'just get a cookie' DS and I love zebra domes. I also adore the chocolate mousse and cocomisu.
Kouzzinas - our new favourite meal. We had a seriously awesome meal here in October. A lot of criticism is given to Kouzzinas about it not being authentic Greek, having only been to Greece once I don't feel qualified to comment but out of all of our meals we only had one average dish - my son's (adult) pork was ok but not amazing. The starter sampler platter was wonderful. The steak was my favourite ever, not huge but very tasty, DH's fish on the bone was he says better than any he has eaten in Europe or USA. DD had the kid's chicken with sweet potato fries and loved it. The puddings we had were the donuts (DS choice but I would have them myself quite happily) the chocolate pud for me, cookies for DH (nothing wonderful these cookies in my opinion but he enjoyed them) and make your own pizza for DD. The pressed pot of coffee and greek wine flight were excellent too. Loved it all.
To be honest although it is very easy to be picky at WDW with food I have only ever had two awful meals there. (Both at 1900PF)
