Our favorite Hollywood restaurants are in downtown.
Go Bistro is my favorite restaurant. It's a small restaurant, with a boring atmosphere, but you can't beat it for fresh sushi/sashimi. The pork belly buns are fantastic. The ramen is also good. There's an option to sit outside & people watch, if you prefer that. IMO, that's preferable, if the weather is nice.
If sushi isn't what you're looking for, C.L.A.S.S Soiree Steakhouse is a good choice. It's another small restaurant that can be loud, but everything we've eaten there has been excellent. Reservations suggested, if not necessary.
Le Comptoir is good for reasonably priced French food.
Tipsy Boar is an above average Gastropub that I would recommend.
At the beach, GG's Waterfront is a good choice. You will need a reservation.
If you want to try really good Cuban food, Padrino's in Hallandale Beach is a short Uber ride away.
You may want to visit Hard Rock Hotel. Be warned that the main casino floor allows smoking. It's hard to avoid it. We rarely go there for that reason. If that doesn't bother you, it's a fun way to spend an evening.
Honestly, there are so many good choices that I wouldn't go to Ft. Lauderdale, unless you want to experience Los Olas Blvd. That in itself could be enough reason to go.
There's also a laua/dinner show in Ft. Lauderdale that recently reopened, but we haven't tried it.
