Three Howard County restaurants make the Baltimore Magazine Top 50 list in the March 2010 edition.
Their top choices are Tersiguel's (#15) in Ellicott City and Iron Bridge Wine Company (#30) and Victoria Gastro Pub (#46) in Columbia. It's a really good edition. There is also a review of Hunan Taste in Catonsville that also suggests some additional dishes to order.
This again me want to try Tersiguel's. I can't rate places I haven't visited, but you can click here for my best restaurants in Howard County.
