Prezzo and Chimichanga restaurants in Lincoln and Stamford are under threat, as the owners struggle with financial issues.
Chimichanga in Lincoln will close, along with all others in the country.
Prezzo in Stamford is closing - the branches in Lincoln and Gainsborough ones will stay open though.
It's hoped taking 94 off the restaurants off the high street will help the chain recover and remain trading.
They'll start closures from April
