I liked cobalt tavern a lot - great food. Desserts are a bit on the ordinary side. Personally, I liked the savory course at Cobalt more than Jianna, but prefer Jianna for desserts. But it's not too much of a difference.
Looks like the judges at the Great Bay Area Chefs' Challenge cook-off picked the Cobalt Tavern chef over Jianna's. (see today's chron)
