We're always celebrating my dad's birthday when we're down there and here are the places we've eaten
-California Grill (view was amazing, but the food wasn forgettable)
-Portobello (Great, but I don't know if it's a great place for a birthday unless you've been there before and it's already a favorite)
-Shula's (great, don't know if it's the best with young kids, but if you love steak this is where I would go)
-Yachtsman (a step down from Shula's but the food is still good)
-Ohana's (great view and the food is great, if your looking for a casual meal this is where I would go)
