Phx Restaurant Week (2008) :
We had a wonderful experience at Bourbon Steak.
The portions were definitely ample (we asked the busboy if they were smaller than usual, and he informed us that they were slightly smaller, but that they increased the portions later in the week, as they had some complaints early).
The duck fat fries were really great (especially the truffle ones).
The service was great (as you would expect from a high end place like this), with no attitude about "people looking for a restaurant week deal".
The food was excellent. I would recommend the corn soup (I have to disagree with ButterflyWest, as it had a huge flavor burst of sweet corn - like it should), skirt steak, and the begniets (which my New Orleans schooled wife said were just like she remembered from her school days). That seemed to be the best combination of items from the menu (although the "Fish and Chips" looked good as well, if people are meat averse).
Drink prices were not cheap (which quickly inflates the bill), but considering the value of the deal, we were OK with that. I loved my Domain Wachau Reisling (it is a new entry on my list of all time faves), but it was pricey for a single glass.
I also loved the interior design of the restaurant. If I won the lottery, I would hire their designer to do my home (we especially loved the white stone walls). The busboy (can you tell we made a friend that night?) told us that they won a big time design award for the restaurant.
Went back for their "Special Bar Burger menu":
We visited this summer, and got a burger off their burger menu (which they only offer in the bar). The place was dead (it was 8:00 on a summer night, so maybe this wasn't unexpected).
The menu offers a choice of meats, and then allows you to customize your burger (with a large variety of toppings), or pick one of their "special burgers" (which had the toppings already selected).
We both decided to make our own. Mine had peppers, avocado, cheese, onions, and ?. I went with the standard beef (they had other options including salmon, chicken, buffalo, and veggie as well). The SO had similar toppings. The burger was great (one of the best I have had). It was juicy, and flavorful (and definitely hand packed). It wasn't cheap (I think it was $16 if I remember - which isn't a bargain by any strech), but the great ingredients, and atmosphere make this a little easier to understand (and this is still a relatively cheap way to enjoy Bourbon Steak, which is super expensive).
We got an order of Duck Fat fries to share, which were an incredible bargain at $5 for the order (and we didn't finish them, so it was a large portion). These were exactly the same as the ones we had during restaurant week, and are really great.
