As a companion piece and counterpoint to yesterday’s “25 Things Chefs Hate About You,” we’ll be running a “25 Things Diners Hate About Restaurants” story next Friday, Apr. 17. Got a complaint — or litany of complaints — about service, portions, prices, or anything else? Shoot it over to firstname.lastname@example.org. The best will get printed in the story, and we’ll keep your name out of it.
