I'm stuck in the bottom right corner. Any hints would be welcome for :
24A To wit it's a Scot's food (4) - Third letter could be P or T
31A 10/03/Antonio? (8) - ?????A?? - Fourth letter could be C or H
17D Basement entry (4) ARE?
22D Warning (almost) ... (6) - N??I??
25D ... with this drink? (5) - ??N?? - Could be PUNCH or TONIC, hence the letters for 24A & 31A. I'm favouring PUNCH.
27D Time to give up (4) - ?E?? - I originally had EMIT in here but that's clearly wrong as 29A ends in E
