Dress is upscale casual. No jacket required but should the dress of clientele is well appointed without going over the top.
As a weekly diner at Liana's, any dress is approriate as long as it's neat and polished. It varies from "upscale casual" to jeans and... I think it depends on the occasion the diners may be celebrating, so they "dress up" or they may come from work or office. Rarely do we see men in jackets and ties.
