Great food as always - I have to have a Double-Double of artery clogging goodness - all animal style. I swear these restaurants are a cult-following on the West Coast. But it's one I'm willing to be a part of. Even the Mormons or David Koresh doesn't have that kind of pull over me.
Definitely go with a Double-Double combo animal style. If you really like the sauce and onions, you can animal style your fries too. But that's a little bit too much of saturated fat for one lifetime.
However, this location is certainly busier than hell and picks up a lot of customers. Steer clear during peak times if you can offset your appetite due to jetlag.
