I went during Restaurant Week for dinner with a few friends from work. My first impression was that the prices were a bit steep. But, because we were doing the restaurant week deal (app, entree, dessert for $30) I wasn't too worried. Until I ordered a martini, although delicious...it was $12 and did not have much alcohol in it.

I chose the beef short rib wellington. The beef was rolled into a ball and surrounded with puff pastry and the risotto tasted like beef strogonoff. While this was good...I could have made it at home.
For my entree I got the Surf and Turf. On the menu is said "Petite Surf and Turk with Filet Mignon Medallion and Sauteed Shrimp. This took petite to a whole new level. The steak was delicious, even though I ordered medium rare and it came out medium. It was very small, which would've been find except the surf part of this meal was two tail on shrimp sitting on top of the steak. This was not much of a meal.
For dessert I went with the trio of mini desserts. It was a long plate with very small portions of four different things; strawberries with whipped cream, lemon raspberry bar, eclairs and coconut truffle. None of the desserts were very good. The lemon bar was extremely lemony and I didn't taste any raspberry. The "eclairs" were stale and tasted like they had been sitting out all day, I took one bite and did not eat the rest. The coconut truffle was extremely bland.
I would expect this level of food from somewhere where the whole meal was $20 including drinks, but after a $12 martini and a glass of wine with dinner I spent $70 and was unimpressed.
I will not be back to XOs unless I'm eating for free and even then I will know that I should only get filet mignon.
