I have no idea how many escargots in garlic butter it is actually advisable to eat, but I assure you it is NOT eighteen.
I went out for a wee work thing the other day, and I only ordered an appetizer (mainly because I didn't want to be there all bloody night.) But of course we were in one of the hotel's restaurants, and the kitchen apparently knew the escargots were for me, because instead of sending out six perfectly innocent snails, they sent eighteen. I slurped those puppies back in no time flat, and if my server had then brought me more? I would have eaten them, too.
But four hours later and I still wanted to die (had felt this way since about number sixteen). My mouth kept flooding with this weird buttery sensation, and if I had burped garlic one more time..... oh but MAN it was worth it.
