I went there with some coleagues a couple years ago and you wouldn't believe the pranks i played on them

An intriguing link! Could I get the fork in my mouth if I couldn't see it? It would be a new exercise in physical coordination.

you could, unless said implement ends up in your nose or someone's else's eye OUCH! But something tells me you're way too smart and point the fork away from your face hahha

the most fun I had with my colleagues was turning their plates just as they said they'd figured out where the food was imagine going for the spuds and you end up pushing your meat off the plate! HECK, they played pranks on me at work, so why not get even

Thanks Ana looks very, very Interesting

I'll pass on both the game and the restaurant.
