Dish one might be served in press bar I suspect (5,4)
I believe the answer is:
spare ribs
'dish one might be served' is the definition.
(type of dish)
'press bar i suspect' is the wordplay.
'suspect' is an anagram indicator (a suspicious or unusual spelling).
'press'+'bar'+'i'='pressbari'
'pressbari' with letters rearranged gives 'SPARE-RIBS'.
'in' is the link.
(Other definitions for spare ribs that I've seen before include "Supporters after free" , "barbecue bites" , "food" .)
