Dine out? Hot food from the east is capital (9)
I believe the answer is:
edinburgh
'is capital' is the definition.
(I've seen this before)
'dine out? hot food from the east' is the wordplay.
'out?' indicates anagramming the letters (I've seen 'out of' mean this).
'hot' becomes 'h' (common abbreviation eg on taps).
'food' becomes 'grub' (grub can informally mean food).
'from the east' is a reversal indicator (on a map from right to left).
'h'+'grub'='hgrub'
'hgrub' reversed gives 'burgh'.
'dine' is an anagram of 'edin'.
'edin'+'burgh'='EDINBURGH'
(Other definitions for edinburgh that I've seen before include "Scotland's capital" , "Lothian city" , "town" , "Auld Reekie" , "fringe city" .)
