Agree with Evan....I would just get a ball or anchor at Biras and dinghy over if you want to check it out. It's a nice bar for a drink but not cheap. No clue how the restaurant is - if I was going to opt for a fancier dinner, I would go to the upstairs restaurant at Leverick if you're there during their season (they will be closing this week for a while).

You could do two nights and spend one in a slip at Leverick and one over by Saba/Bitter End/Biras and dinghy around to Saba, Fat Virgin, etc.
