Appetite in downtown San Diego has served breakfast and lunch from 401 West A Street since 1998, running a weekday counter-service kitchen in a ground-floor office-tower space near the Columbia district's courthouse corridor. The Black-owned restaurant builds its lunch menu around signature sandwiches — the avocado club, jalapeño tuna melt, chicken Mediterranean, and a Cuban pressed on French bread — alongside house-made lasagna and rotating soups, an approach to midday dining that parallels the weekday sandwich-and-soup format at Plaza Deli in the B Street tower one block south. Breakfast burritos with Applewood smoked bacon, black forest ham, or carne asada anchor the morning menu, served alongside eggs Benedict skillets and made-to-order omelets. A catering operation runs parallel to the walk-in counter, assembling platter packages that combine half-sandwich assortments with signature salads — Cobb, strawberry fields, roasted beet — cookies, and chips for office-floor deliveries. The health department scores this kitchen at 100 out of 100, a benchmark that few downtown lunch counters maintain consistently and one that reinforces the from-scratch preparation standards also upheld by Krisp Beverages + Natural Foods in the same downtown office-lunch corridor. The most complex catering package is the Signature Sandwich Tray — ten half-cut gourmet sandwiches served with a full-format salad and accompaniments, assembled to feed a conference room without advance reservation.
