Big transitions can be almost effortlessly smooth -- when Don Johnson went from cop to 80s pop star, he didn't even have to change his clothes. Moving into music without changing its clothes, Donovan's, with Circle of 5ths. Named for the geometric representation of the 12-tone chromatic scale (duh), Circle marks Donovan's first non-steak venture: a pillared cavern devoted to musical entertainment, though still steeped in their traditional-meets-modern style, with dark wood & leather furnishings matched against eclectic art from surrealist to abstract, plus a series of small, intricate metal sculptures of musicians, none of whom are Joe Walsh, because he turned to stone. Live music of some form will be heard every minute they're open, with the 4-8 slot filled with instrumental "happy hour background music" (flamenco guitar, sax, etc), giving way to livelier fare like Motown, jazz, and battles on their dueling "Slam Grand" pianos -- so you can expect Red Red Robin Ventura to come Bob Bob Bobbin' Along. The twin wood-topped bars sling cerveza standards, 25 wines by the glass, a whopping 42 whiskeys, and a martini-focused specialty cocktail menu, stretching from the margarita-in-witness-protection "Behind the Grind", to the vodka/peach/basil "Hit on all Sixes", though martinis tend to make you hit on all Fours. As for music for your mouth, they're concentrating on share-able "heavy bites" (still smaller than traditional Donovan's portions), from Yellowtail with Baby Beets to Prime Filet Philly Cheesesteak -- sure to have paramedics looking for a heartbeat.
