I've been to Park on Fremont more times than I can count, and I've never been disappointed.
The service is great. As the other reviews have said, you are greeted almost instantly upon entry. It's got a funky and hipster vibe which I love.
As for drinks, both happy hour and brunch drinks are great. Trendy drinks, but there are also the classics. The last time I was there for brunch, I went for the breakfast sandwich which was divine.
The only thing I caution is that there are parking issues. Be prepared to walk a few blocks.
