"Low Spark is my favorite "wait-for-my-table-to-be-ready" bar in OTR. Anyone who has every tried to eat in OTR on a Friday or Saturday night knows the struggle, and then what do you do when the bar at that restaurant is full?! The answer is walk down to Low Spark, conveniently located right by many of my favorite restaurants.  It's layout, which is one single bar wrapped around a giant fish tank, gives every couple or small group just the right amount of privacy, maintaining a casual, yet moody, atmosphere. Although their excellent bartenders could probably handle a crowd, this wouldn't be my top choice if I had a large party. Drinks here are top-notch. Be sure to try one of their handcrafted cocktails. I have been getting the Old Fashioned here just for the baseball-sized ice sphere they put in the drink."
