I would suggest for Pizza, Palm Springs Pizza on the Northwest corner of Congress and Forest Hill. Even though it is a chain, I love Carraba's for Italian. If you just want to party in a noist atmosphere and decent food, I suggest "Daves Last Resort" on lake Ave. in downtown Lake Worth.
Best by far for casual great food is food Shack in Jupiter..although getting in can bea challenge.
Capt Charlies Reef Grill in Juno.
Spoto's Oyster in PBG
Taboo in Palm Beach..eclectic menu..great (older) people watching)
Solu on Singer Island..$$$$ Asian/Caribbean
PA Barbecue...good cheap BB ribs
Vic & Angelos....decent pizza good crowd
Thaicoon on Northlake
