This is a bit of a difficult review to write because when I ate here it was way past midnight and I might have had a few libations. As a possible result I thought the burgers and fries were excellent!
Burger Bar has quite an extensive menu and our group of 6 took full advantage of that. Each person ordered something different. My burger was cooked to a perfect medium-rare; it was excellent and was very juicy. The sweet potato fries were good and hit the spot although the ranch was...eh. The others in my group seemed to enjoy their burgers, fries, and shakes. One of them had some sliders that looked very tasty.
The service was attentive and very accommodating especially considering how "sauced" our group was. Even though the food wasn't too greasy it really hit the spot after a LONG night at the tables. Fortunately I had enough leftover for a late night snack; tip included :)
