The Seafood Station, an old converted gas station on hwy 101 in Florence fits in the "Dives" category. It's pretty tacky (ie: trashy looking) inside and out, but their seafood is pretty darn good.
Forgot to mention Leroy's Blue Whale earlier. It's located on hwy 101 in Yachats. I can't comment on anything but their fish and chips b/c that's all I ever eat there, but I think it's the best on the coast!!
Rhododenrons: You obviously know Florence is the City of Rhodendrons. The problem, if you want to refer to it as that, is Florence is REALLY known for it's native population of rhodys. Native rhodys are all white to light pink and grow more like trees than shrubs. Many are 30-40 foot tall!!
That being said, make sure and take a swing through Jessie Homeyman State Park, 3 miles south of Florence. Inside, and along hwy 101 through the park, you will find the largest number of native rhodys in the area. Because of all the rain we have had, it looks as if the rhodys are on track for a mid-May bloom. When are you coming? May 18-20 is the 105th annual Rhododendron Festival in Florence.
