Entertainment venue in essence, having horrible glitch (5,4)

Ross

I believe the answer is:

night club

I'm a little stuck... Click here to teach me more about this clue!

'entertainment venue' is the definition.
'night club' can be an answer for 'venue' (I have seen 'Late venue' mean 'night club' so perhaps 'venue' could also mean 'night club'). I am unsure of the 'entertainment' bit.

'essence having horrible glitch' is the wordplay.
'essence' becomes 'nub' (synonyms).
'having' is an insertion indicator.
'horrible' indicates an anagram.
'glitch' anagrammed gives 'ightcl'.
'nub' enclosing 'ightcl' is 'NIGHT-CLUB'.

'in' is the link.

Can you help me to learn more?

(Other definitions for night club that I've seen before include "Bar, disco, etc" , "Venue open till late" , "Late entertainment spot" , "Scene of late hour socialising" , "Place open late for entertainment, food and drink" .)
