Be prepared for traffic jams everywhere. Long lines at restaurants. There’s good places to eat but there’s not many on the water. Theres a nice new seafood place in Osprey a few miles south between sarasota and Venice on Black burn Bridge called Casey Key Fishhouse. https://caseykeyfishhouse.com/
I have not been there because I don’t get down there very often but it looks intriguing . Pretty area.
Ringling Museum is a must see. One more thing…bring money, lots.
Casey Key Fish House. If you are seated before 2:30 on Sunday, you can get a grouper dinner for $16.99. Sometimes it is snapper, but the ambience on the water is old Florida. Aross the parking lot is a Tiki bar with great margaritas and after 3:00 there is a band and you dance in the sand next to a small beach! I love taking guests there by pontoon boat from Freedom Boats in Venice.
