Definitely big enough to share, at least in the opinions of lots of people, although not so much because of the sheer volume of food, but because of what it is -- i.e., a fairly massive and rich slab of bread, stuffed with bananas and covered in cinnamon/sugar. I have tackled it myself (and won), but it can be too much of the same bite over and over again for some people, so sharing tends to be a favored approach to this item. Toss in an extra side of bacon or potatoes, etc., and you'd easily be fine.
