I don't think much out there is totally angle proof, however, if you manage your space correctly you can make most anything angle resistant. Also I would hope you brought more than three effects with you. If the next table seems a little nosey, use less angley props or routines.

I think it is a matter of starting off with safe tricks, and if other tables don't seem to be taking much attention, and you are sure you won't get sprung, then give it a go. If you have some doubt about giving it away, then don't do it. Best of luck!

I agree with angle proofing your routines. Anyone seeing what you are doing totally takes away from your magic and gives your spec's the opinion of you just toss things very well. If you think spec's do not talk to each other, think again. I was at a restaurant and had the magician there perform for my grandchildren. After he was done "AMAZING" our table, the gentleman at the table directly behind me made the comment to me that he saw just about everything the magician did. Unfortunately this distroyed this guys perception of the magician. From the front, his presentation was very good, from behind he crashed and burned. Be aware of your surroundings.

Magically,

Yes. I feel it is important to angle proof your Magic. There is one routine that I do which I have made angle proof by changing a few moves. However, if I know everyone is right in front of me, I take one move out of the routine. I also sometimes just use my body to block spectator's views from behind me. However, the easiest method I have found is to just choose Magic that is angle proof. Luckily there are a million tricks and routines you can perform and I pick out the ones that are easily reset, angle proof and fun to perform. Cheers!

Wow this took some digging

Invisible deck... only bad angle from below!
