C.A.B. is a marketing brand and is often in the top third? of choice and could? be in the top quarter overall.
Regular choice could be anywhere in the whole spectrum of the upper 70%,good or bad.
If the price is not much more than choice in general,most folks would say it is worth the little extra cost.If you are in the comp business,you might feel it is worth a little more to you.
Some will be better than others and that is good restaurant size,but small for many comp cooks.
