Evening food?

I keep going back and forth on this so any suggestions welcome!


We are having a later wedding - registry office at 4.30pm. Nearby pub function room after, so arrival by 5.15, plan to sit down for food around 6-6.30pm. it's a small informal wedding (60 guests for the whole thing, no additional evening guests). We are having a carvery dinner followed by dessert, no starter. We have wedding cake that will be sliced up for later in the evening and we are doing a chocolate cart. What other food and at what time? Would you expect additional food? We originally thought we might have bacon butties bought out around 9.30 but this feels too soon after a roast . We are planning on wrapping up the whole thing by 11pm
