Great report, very fun to read.
I am always amazed since I live in Northern CA, and very seldom eat at In-n-Out, although I really like, it. BUT I almost always stop at the In-N-Out (in Mill Valley on 101) for a burger and a lemonade on my way home from the airport after flying back from being out of the country.
I leave for LHR on Monday so I am looking forward to some good Curry and fish and chips. And I guess you will find me at In-N-Out on Thursday once I get home.
Thanks for the report ^
