Depends on the circumstances, what YOU are known for doing, and whether or not you feel like playing the role of a trained monkey who will perform on a whim.
Nine times out of ten, the reason our "friends" invite us to a party or dinner, is for FREE Entertainment... they are using you! The reason being is quite simple; they know that you have an ego and thus, a "need" to show off and thus, with just a bit of encouragement, you'll do a free show right there. Especially if you fit into the classic mold of the "magician" and have your pockets filled with odds & ends; at least one or two decks of cards, TT, Sponge, Coins, Dice, ITR... the list is quite amazing and of course, includes no fewer than one special wallet and one special business card holder... after all, we must live up to the Boy Scout motto and BE PREPARED!
Yes, I'm being a bit crass but we all know people that fit this particular mold and have probably done it more than a few times ourselves.
So when it comes to your question you have to weigh out a few important issues;
1.) What kind of material or image do you want to be known for doing?
2.) What are the circumstances/environment in the situation?
3.) Are you a trained monkey?
With the first, we need to look at the sort of things we normally perform; if you are known and pride yourself for your coin work, then you want to do something simple with coins. Needless to say, if you are known for card magic you would go that course, HOWEVER!!! This too offers room for possible division;
"Are you just a cardician or are you building the image of being a Card Shark and Gambling 'expert'?" Once you know this then plan accordingly.
When it comes to the Environment, just going out to a mixer or being at the pub can be two entirely different things.
I've attended socials that were quite formal (black tie & all) while I've also been to those with a more kicked-back Hawaiian or Southern California Beach Party kind of setting. Conversely, you have the pub or dinning settings which can be anything from a Sports Bar to what we call the "White Table Cloth" quiet dinning environs.
I don't think you would get a positive reaction doing the Goshman Magic Ding Dong routine when working the latter even though it would probably do quite well at the Sports Bar and more typical pub... so long as it's NOT a "family" type establishment (you also need to be cautious with "blue" magic like this, when working certain other facilities; I know of a lad that got rather
bruised up doing this very routine in a Biker's bar).
The "Trained Monkey" syndrome is a tricky scenario in that we do need to have those situations in which we "do our thing" but at the same time, we need to not seem "hungry" to show-off and when we do, we need to remember that "less is more!"
I have shrugged off such requests with the following lines...
Maybe a bit later
Not right now, I'm trying to relax and enjoy myself
I too drunk at the moment
Ok, but only if you are willing to give me a free (insert, whatever their job is) next week when I drop by
In that I'm best known these days for being a kind of curator of things bizarre and paranormal, anything I demonstrate under such settings tends to be done as a kind of improvisational experiment and deliberately so.
Why?
I'm not a "magician" e.g. it would make far more sense if I'm not prepared and need to borrow items and present everything in a seemingly unplanned, unrehearsed manner (though the opposite is quite true). Under such auspices I can quickly generate that investment of belief and plausibility... not just the anticipation that something "might" happen but the vested desire by the gathered, for it to happen. In the case of someone doing mentalism, this isn't just priceless, it's a good 90% of what makes the effect.
Now most everything I do under this setting is exceptionally simple... even when I did traditional magic, the bits I'd do were simple... exceptionally simple! The classic two in the hand & one in my pocket routine, for an example... then again, I'm guilty for doing Zombie Baked Potato as well
I hope this mini-lecture helps get those creative juices flowing for you
