I would say allears is more update. I don't normally look at intercot so checked out a few of the menus that I knew had a "standard" entree dropped about year ago, and on intercot they still showed that entree. Mind you they weren't terribly out of date and some were fairly current. Nice thing about allears is that they show the month they were last updated.
Which resturant(s) are you looking for? I just returned with copies from several returants - Coral Reef, LeCellier, O'hanas, CRT (dinner before 2/1), and Spoodles. If you want specifics on any of those, just let me know.
