Was very disappointed to find the Dallas HRC had closed before I finally got out there. Ho Hum. My list so far:

Los Angeles (at the Beverly Centre, now closed, I believe)
Chicago
New York
San Francisco
Tokyo
Sydney
Amsterdam
Madrid
Barcelona
Paris
Cologne (bought the tee with the German spelling )
Roma (where they'd sold out of the standard tee in my size ).

Not many really but I'm glad to say I've never had a bad meal at one.

(and to think, I only popped by to see if a superb eatery I'd found in Rome had been mentioned in these forums).
