Here is a fun little piece that discusses the strategies employed by owners of all-you-can-eat buffets and some ways to work the system (via Neatorama).
By and large, though, the curious economics of AYCE deals (did you know that if the buffet costs more, you’ll find it tastier? It’s true!) allow restaurants to take champion eaters in stride. “For every big, hungry guy or gal who can really eat his or her weight in crab legs, buffets count on a few who won’t,” wrote Bourree Lam for a column on the smorgasbord business in The Atlantic. It’s this law of averages that makes it difficult for any random customer to get the boot over a massive meal — even if that’s what they’ve set out to accomplish.
