You might get more responses over on the Restaurants board. And FWIW, a friend just tweeted that right now there's a 2 1/2 hour wait to get into BOG for lunch.
GO EARLY!!
I lined up at half an hour before the restaurant opened, and got in right at opening and was in no problem.
BOG opens at 10:30 am, and the earlier you get there for lunch, the better!
