Ten Tables, Craigie on Main, or Salts?
I and my SO had a wonderful dinner at Salts a while back. The duck for two was amazing, as is the atmosphere. If you're looking for more of a candle-lit, romatic vibe, I'd go there. We actually walked across the street to the bar at Craigie afterward for drinks, which was a nice way to end the night.
Craigie on Main is the best of this list. I'd also call it Boston's best restaurant. It will make a wonderful nice Saturday dinner.
All are good, though. Salts is more formal, a more romantic date, serving more traditional French fare. Ten Tables is a price point lower than the other two and serves slightly creative bistro fare. I'm increasingly considering Craigie in its own class.

I've eaten at Cragie, Salts and Ten Tables (JP location only.) Salts was my favorite without question. (I wrote a long review about my last meal at Salts and posted it on CH. You can search for it if you're interested.) However, if price is a consideration, you can probably spend a little bit less at Ten Tables and still have a very nice meal.
