I usually go to HRC if there is one available...not so much to eat as to collect pins. They are a good souvenir as they don't take up much room in the suitcase. My list so far:-

Sydney - My home town and close to work
Melbourne
Surfers Paradise
Singapore
London
Paris
St Thomas
Amsterdam
New York
Chicago
LA
New Orleans
Las Vegas
Newport Beach - A sentimental favourite
La Jolla
San Diego
Tijuana
Aspen..which closed a while back
San Francisco...the old location
Honolulu
Hollywood
Bali

I am planning on a few more visits shortly..I hope
