I feel the meal portions at CG are pretty substantial regardless, but we order an appetizer anyway. We share the flatbread and have still had a piece or two to spare. If a person wanted to make a meal out of - that would be an option as well.
If you're planning on ordering an entree definitely share the flatbread - I wouldn't let wondering if you will finish it stop you from ordering it though - if anything have them box it up for you - makes a great breakfast the next day!
