Hands down the best burger I have ever had. You can select a burger from the menu or build your own, with extensive choices of bread, type of beef (or chicken-- but you're at a place called Burger Bar...order beef), cheeses, veggies, sauces, and side (the sweet potato fries are awesome). I had the Nature Source beef (100% vegetarian fed) medium rare and it could have walked off the plate. I'm drooling just thinking about it.
Perfect place for a casual dinner with friends.
