Chris Dantley, editor of the Zagat restaurant guide for New York, received mixed reviews Monday from women who have dated him. ''Well-heeled' 'outgoing' man offers pleasant-enough company but 'loves to talk about self' and 'blows half his jokes,'' reviewers said of the 35-year-old Dantley, located on East 81st Street near Third Avenue. ''Free smiles' and 'snappy dress' don't go far enough to offset 'strained compliments' and 'inappropriate come-hither looks.'' Dantley's midsection was also panned as 'overly doughy.'
