I agree - it's rather a vague question - and almost certainly not worthy of an answer.
Will the answer 'yes' be sufficient for you to now go out and purchase this effect??? I think not.
There's a lot of knowledge on sites such as eMagictricks.co.uk or Penguinmagic.com.
The Club Sandwich routine is outlined there in reasonable detail - and further information can be 'mined' from fellow magicians by structured questioning.
Pedey's right - Yes would be a good answer. But take note: it's an objective opinion - eg. if you asked a room full of people if they preferred Coffee to Tea, and they all just answered either 'Tea' or 'Coffee', all you'd find out is which one - not
why.
Hope this answers your question.
