I don't think you mentioned Lakeside in the American City Bldg. They always offer regular coffee as well as flavors of the day, and they make a killer bacon, egg, and cheese bagel.
My favorite has always been Bean Hollow, on Main St. Always fresh, and the smell of coffee beans roasting adds to the appeal!
Love the podcast about coffee in Howard County. Unfortunately, Java Grande on Rte 40 closed. The pottery shop down the row is going to move there, expand, and offer coffee.
Consider trying Riverside Coffee in Columbia or Sidamo at Maple Lawn in Fulton. I like the coffee at both, although I'm so addicted to caffeine that I'm a bad judge for coffee. Riverside is on the side of Dobbin that flows a little faster than Panera Bread.
Also, you can buy that Orinoco (I think) at Mom's Organic Market in Jessup.
I've become a real fan of the Little French Market in old town Ellicott City.
Have you tried Nora Cafe in the Normandy Shopping Center on Rt. 40? It's a little out of the way but still in HoCo. Definitely worth the trip for VERY tasty coffee and really good breakfast, lunch and dinner food.
