Regularly visit hectic hotel to eat out (4)
I believe the answer is:
etch
'eat out' is the definition.
(I've seen this before)
'regularly visit hectic hotel' is the wordplay.
'regularly visit' means one should take alternating letters (letters taken at regular intervals).
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
The alternating letters of 'hectic' are 'etc'.
'etc'+'h'='ETCH'
'to' is the link.
(Other definitions for etch that I've seen before include "Corrode" , "Carve into surface of something" , "Imprint vividly" , "Engrave metal plate using acid" , "Carve (design) on a surface" .)
