Don't think I have. I'll check it out next time I'm in cambridge or bluewater (My closest it looks like).

Thanks for the recommendation

Cambridge has one on Regent Street. Good burger; you won't find a decent milkshake, though.

Bob Bob Ricard are somewhat OTT, but still their milkshakes are divine and rival what you can find in NYC: http://maps.google.com/maps/place?cid=5205391226741305498

Shame you have to go to a high class restaurant/cocktail bar for it though.
