Guests for dinner. How much attention do you pay to likes and dislikes?

Yes I only cater for allergies and I don't know any vegetarians so no problems there.

I don't ask and don't worry about it. Occasionally guests have let me know in advance that they really can't eat a certain thing and if that happens of course I'll avoid it. I would never serve something like offal or even certain seafood (which I love), because so many people don't eat them. But, otherwise I just provide enough food to make sure no one will go hungry, unless they're incredibly fussy!

The last guest I had for a meal I was cooking Sunday roast. I did ask if there was any veg the person didn't like. As we eat all kinds of veg it was easy to cater to their tastes.
I always do two desserts when we have guests.
If family come and I have nothing they like, we either eat out or they go to the shops! I certainly don't stress about it.

I only cater to food allergies and will make something different for vegetarians. I am allergic to fish and have lesser problems with some other foods but I always make sure the host knows this as soon as an invitation is received.

One of the reasons I don't entertain if I can help it is because I tie myself up in knots worrying about things like this. I have family staying next week and I'm already having a panic attack about it and what to get in just in case they want this that or the other .. and thats just for family!!
