By a strange fluke I've eaten dinner at Chez Henri in Cambridge 3 times in 3 weeks, including last night. All fine, if not truly inspired. Last night I ordered the steak frites, medium rare, and received the steak frites, well done. As soon as I pointed this out to my waiter, he said "Oh my, you sure did". No, "umm, are you sure.." or other stupidity. He whisked it away. In less than 10 minutes I had a most beautiful steak frites in front of me, and the chef threw in a dessert on the house. It was a very pleasant experience on a Sunday night. The restaurant was only half full when we arrived at 7:30, there was plentiful free parking on Mass. Ave., and the mojitos up to snuff.
