Laura Goodman, co-owner of Carlini restaurant in Market Place, posted on a Facebook page how a ‘pious, judgmental vegan’ had gone to bed ‘still believing she’s a vegan’.
Carlini, which also has an Albrighton restaurant, received a flurry of online messages following the posting and its Tripadvisor and Google pages were flooded with comments.
Police are looking into death threats made to Ms Goodman online.
Today a statement on behalf of the restaurants said: "Laura Goodman has today tendered her resignation from Carlini and the board of directors are currently considering their options.
"Whilst this process is being completed, Laura will not be working at either of the restaurants, which will reopen later this week.
"As part of a pre-planned recruitment drive, Carlini is also recruiting for an additional head chef to work across both its restaurants in Shropshire."
Yesterday the restaurant today admitted the comments by Ms Goodman were 'ill-judged' but said they had been misconstrued by online commenters and that no meat was used in any of the dishes.
The jibe came after Ms Goodman created a special vegan menu for a party, only for them to then choose to eat a cheese-based pizza, the restaurant said.
A spokesman for Shropshire Council’s regulatory services department, Gareth Profitt, said: they were investigating the situation.
