New Miami Beach info

I know there's a lot of Miami posts. Just looking for current information for when I'll be traveling in March. I'll post my questions here as I do my research.

1. Has anyone tried the new House of Dog restaurant? Looks good! What did it take the place of?

2. For Friday night I think I'm going to eat at Rare Steakhouse, but is anything open for Saturday other than Tower on the Bay (formerly Tower 41)?

3. Anywhere new to try out? I know it's not new but Thai Treat is getting a visit - we love that place. We haven't gone over the restaurants on Aventura yet so we may venture out there as well.

Thanks.
