Not sure what you mean by "reasonable," but Borago, on 30A near Grayton,is a good choice, as are several other non-fru-fruiy restaurants. Stinky's Fish House on the west end of 30A gets lots of rave revues, as does Bud and Alley's. Cafe Tango for a more quiet romantic evening, or if you want to find a mostly local crowd with good burgers and beer, and live music, head over to Salty Dog Saloon, also on 30A, next to Cafe Tango. I think Duke and Kyle start playing around 9pm (they play a wide variety of music, much of which they or their friends wrote. Both have played on stage with some major performers on numerous occasions). If you are up for the best BBQ in town, head over to another local favorite, located on Hwy 98, maybe one mile west of Hwy 393, to Jambone's -- Very casual atmosphere, the best cue, plus other foods, and a wide selection of beer and TVs.
Maybe I will see you at one of the aforementioned places tonight! I will definitely be at one.
