Sorry for the late reply to your question, but it was the Renaissance.

As to Shanghai, we did find the Coffee Bean and Tea Leaf had free wifi and great coffee. Try their breakfast specials with free coffee refills and toast, quasi eggs benedict etc. I liked the sausages a lot. But suspect they are not kosher per the Coffee Bean in the US.

By the way, there is a lovely expats party/brunch at the Coffee Bean in Xintiendi shopping center (center is well worth a visit-nice use of old buildings and new construction-and try the Crystal Jade dim sum place--excellent) near French quarter. Free except for the coffee (ask for your ten per cent expat party discount) from aroound 11am to 3pm on Sundays. Very pleasant and sociable group.
