We were out looking for a late night meal and being right downtown there wasn't a ton of variety, but El Caballito was right across the park from where we were staying and it was open until 1 and wasn't fast food, so it met the bill. It's a pretty cool place when you walk downstairs. It has a great bar and by the looks of it, a great tequila tasting room. There's also a great outdoor patio in the back that gets really busy after midnight. Good drinks, awesome service and the food, although not the best tacos I've had, certainly fed our appetite and left us happy and content. Also, there was an awesome DJ the night we were there.
