I wouldn't expect a full meal at a 2pm party unless it's written out on the invite; at that time I'd just expect some cold appetizers, veggie, fruit and cold cuts/cheese platters, chips and what-nots and then cake at the end
At my son's 2nd birthday party (at 3 pm), we had veggies and dip, crackers with cream cheese and tomato preserves, fruit, and snack packs with Annie's bunny crackers, applesauce, and Rice Krispie treats for the kids, plus cupcakes.
