We spent a week in St Augustine in January and had two great meals at Creekside. We liked it the best of places we tried even though all were good (Harry's, Salt Water Cowboys, Athena's). The location is what makes the place. It's a rustic house-like setting right on a creek outside of town. One of the nights we got a seat on the porch right on the creek/river-- beautiful views around sunset. It was cold when we were there but they have lots of outdoor seating that would be good in the summer.
The food is really tasty and the meals come with all the fixings. Our favorite was the "Plank Chicken" which was chicken with great mustard sauce cooked on a wood plank. It was totally moist and delicious. We went there twice because it was so nice a place.
We went to the Salt Water Cowboys owned by the same company and thought Creekside was better even though both were good.
