I really like Delaney's. It has a quiet, intimate ambiance perfect for a date or special occasion. Being a little less dressy than some of the other steak houses I've been to, it's a little more relaxed, which is a plus in my book.
The small dining areas keep you from having too many people, and their conversations, around you. Two servers per table help to keep things moving in a timely fashion.
Then there is my favorite, the Ostrich Wellington. It's actually an appetizer, but it's kept me coming back for more since the first bite. Well worth a visit just for this.
Maybe even try their homemade Tiramisu for dessert...
