I've been here twice - once for food, and once for the nightlife.
Food: I got a cheeseburger for lunch one day, and it was...well, it was fine. Nothing to write home about. I had brought my laptop so I could study vocab for the GRE (mooching off of the nearby Starbucks wifi), and they were very nice about letting me sit there and work (the place was half empty, otherwise I would have moved once I was done). My waitress was a little rude at the start of my meal, but made up for it by being nice and attentive the rest of the time. Perhaps she had just been irked by her previous customer?
Nightlife: Two words: weird crowd. My roommate had warned me of this, but we stopped by anyway because I couldn't resist the name of this place. Yes, it's a dive bar, but still...lots of single older men, and not the good kind. The bartender was nice enough, but my roommate and I each got our one drink and left. I will say that the bartender also didn't know what a 7&7 was - but maybe he was just new?
I probably won't be back to Nauti Mermaid, but I do still love the name...
