Wylder's at Jupiter Pointe Marina on Hwy 1 in Tequesta. Live music most nights (and sometimes weekend days) they even have a pool to swim in while you eat/listen
Tiki 51, just up from Wylder's, music Thurs-Sun evening
Corners on Indiantown in Jupiter. Open Mic on Tues. Music other nights but not sure when.
Sandwater Grill, in same strip shopping area and Radio Shack on Hwy 1 in Tequesta. Music on the weekends and sometimes week nights.
Guanabana's, A1A in Jupiter(across the street from Schooner's) live music on weekends for sure. Sometimes on weeknights. This place can get VERY crowded, but the ambiance is cool.
Lucky's Bar and Grill, in the Publix shopping center on West Indiantown in Jupiter Farms. They have groups in on some week nights and an open jam on Sunday afternoon (I think it's Sunday for the jam, but might call to verify)
Uncle Mick's in same shopping center as Panera Bread on Indiantown. Live music Thurs-Sun.
Rooney's in Abacoa. Live music Thurs-Sat. Nice to sit outside and people watch here.
Sailfish Marina on Singer Island. Live music on Tues nights. The food in the main restaurant part is pricey here, but if you request to eat at the bar or outside tables, (where the music is) you can ask for "the sandwich menu" (MUCH cheaper!) they usually have a little craft fair type thing going on too. Love being able to watch and feed the fish off their dock. It's like a big ol' aquarium!!!
I've been to all of these places except Lucky's and Uncle Mick's. I liked them all, but it doesn't take much to amuse me. You might want to call ahead to check and see who/what type of music is being played the night you want to go.
