I've eaten out at 3 places since we've been able to. I would go back to one of them any time and another I would try again. I wouldn't touch the third with a barge pole.
Ist - took names and numbers on arrival, open air, masses of space between tables, lots of shade, cleaning regularly, code for ordering and paying using phone on table, table service, staff kept their distance, sanitiser in loos and 2 at a time only (was a posh portaloo cabin). I've been there twice and it was lovely.
2nd - took names and numbers, outside (not as much space as the first one, but ok), staff wore masks. The only thing that wasn't so great was that you had to go in to pub to order, but they had a one way system in place.
3rd - outside, sanitiser on entry, gave names and numbers, didn't have to go in to order food or pay. However the tables were in the same place as they always are and social distancing was very tricky. We chose a table that looked a bit further from others, but it was too near to the paying area where people queued the entire time we were there. For some reason hardly anyone made an attempt to social distancing and there were groups of older teenagers at tables who were clearly not from the same household. Didn't enjoy it at all and decided just to have a drink in the end and leave.
Personally I wouldn't eat or drink inside at the moment, so most restaurants are unavailable to us right now.
