Monroeville police say 20-year-old Lynaa Eva Dobbins attacked four female guests at the restaurant about 7:30 p.m. Saturday.
Investigators say Dobbins was apparently upset that her son's father had a new girlfriend at the party. Police say Dobbins cut one woman's ear with a knife and hit another with a brick. She's also accused of hitting two other women in the brawl that ensued.
Online court records don't list an attorney for Dobbins, who remained jailed Monday.
She faces a July 17 preliminary hearing on aggravated assault and other charges, including stalking her ex-boyfriend.
