Have a meal in Chelsea trattoria (3)

I believe the answer is:
eat
'have a meal' is the definition.
(I've seen this before)
'in chelsea trattoria' is the wordplay.
'in' indicates a hidden word.
'EAT' is hidden within 'chelsea trattoria'.
(Other definitions for eat that I've seen before include "Partake of" , "tolerate in diet" , "Gobble up" , "get stuck in" , "Dine in a restaurant" .)
