The popular value menu will continue, giving fans pricing options. Healthy choices like hummus and carrots and ranch will also be available.
There will also be a return of the value beer menu, with 12 varieties available at various locations priced at $5 and $6 for 12-ounce cans.

Players to watch: 2023 roster
Plenty of familiar faces return to the lineup for the Mariners this season, although fans can expect a few newcomers to provide valuable contributions in 2023.
Julio Rodriguez, of course, is now the unquestioned face of the franchise in center field. After winning Rookie of the Year in 2022, J-Rod has his eyes on a potential MVP campaign.
Teoscar Hernandez is likely to be the most successful new position player for the Mariners after coming over in a trade from the Toronto Blue Jays during the offseason. Hernandez is projected to hit 30 home runs in 2023 according to FanGraphs.
Luis Castillo and Robbie Ray form one of the league's strongest 1-2 punches in the starting rotation, but the first full MLB season for former top prospect George Kirby will be the most intriguing storyline of the '23 season.
Kirby put together a strong rookie year after debuting in May and punctuated his resume with a postseason save against the Blue Jays and a dominant seven-scoreless inning performance against the eventual World Series champion Houston Astros in the playoffs.
