Hello Ville_Valo!
Let me share my 2 cents about routining/ restaurant magic effects: First the tricks have to have little or no reset. Next they should have little or no angle problems. Your tricks do NOT have to be in perfect flowing order. If you first trick is flashy and visual and you last trick is a haymaker, you have a good routine. (But, if you can make them flow as much as possible.)
1.Your first trick should be somthing quick, flashy and visual. A few good openers are; vanishing silk, producing four quarters, Paul Harris vanishing deck (The deck is then produced from case. Learned in Art of Astonishment) Let's pretend you used a stealth pen, *you walk up to table* Can I borrow a dollar? The people would think that you are going to steal their dollar.

NOT GOOD!
2.Your middle trick can be more lenghty. Most magic tricks fit into this catorgory. Stealth pen is good. Also when you ask for a bill, they know you are a magician after seeing you first trick.
3. Your last trick should be the most amazing effect. Since you self levitations wouldn't work, the next most amazing trick is the levitating bill. (if you used the stealth as closer and levitating dollar as middle, all they would be thinking while you are doing stealth pen is, "How did he get that bill to levitate?" That's why you need the effects to build.) Some good closing effects are; sponge balls with kicker climax, Acr with card to wallet, omni deck, spellbinding boxes.
I hope I helped,
