Place to serve beer and also, regularly, appetisers (5)
I believe the answer is:
tapas
'appetisers' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for tapas that I've seen before include "Mediterranean appetisers" , "Spanish savoury dishes" , "What's served in Spanish bar" , "Spanish snacks" , "Small Spanish dishes" .)
