I agree that the really high end places will set you back more than $200. It is near $100 each for most degustations around town and then you add in drinks and wine...I think we spent just over 300 at Spiaggia recently with wine and multiple courses. After all, you are going there to try the food, it is hard to limit yourself to a few tastes.
For the money though, I wouldn't go back to Spiaggia. It was good but it didn't bowl me over.
You mentioned Kevin; that is a good idea and not too far.
Across the street, you'll be under budget at VTK (Vong's Thai Kitchen) and still have a good meal with asian flavors. Great appetizers.
You can spend $200 at Shaw's Crab House pretty easily, also not far from there.
