"A Japanese restaurant chain specializing in udon noodles is now open in Kenmore Square. Tsurutontan, which has roots in Osaka and has a dozen outposts throughout Japan, opened inside the Hotel Commonwealth last week. The star of the show at Tsurutontan is the thick, slippery udon noodle: Its menu features more than a dozen varieties, including beef udon in dashi broth, cold udon made with a spicy sauce and caviar, and lots more." - Terrence Doyle
