Hold up, hold up. Definitly NO to the five tricks. You need a minimum of 2 yes count 'em 2 routines 8-10 minutes in length along with 5 extra, stong effects for special guest (something like Carl Andrews cups and balls or a bill in lemon routine).
My reasoning for saying two is:
1. You're doing magic for people waiting for their food, so a lot of times that won't be the case for two tables next to each other; and
2. if it is a lot of the time the ppl are like "can you do that trick with the four kings that you did for them" so you just do the routine over possibly tweeking it a little. Thats my two cents
Example of routine that could be repeated (granted that the table next to you wasn't burning your ever move before, which they likely weren't)
No opener needed they already know your the magician
