The patio area is very nice with lots of seating, a big gigantic fountain in the middle, and some misting fans to keep you cool while you enjoy their Happy Hour libations. My two gripes for Abuelo's outside area: 1) A BAR.....seriously, this place is nice and should have a bar outside. Waiting to get a drink outside proved to be a little more than I would have really like, but was OK. 2) put the misting fans on 'rotate'. If these fans don't rotate outside to keep your patrons cool and happy, don't be a cheap ass and replace these.
We weren't there for the drinks or the food (but that was the bonus), we were there for The Brew (http://www.brewmusic.com)! I have seen these guys a couple of times before and the company I was with has followed them for more than a decade. From the Valley to 'Keepin'g It Weird', I found this setting at Abuelo's to be way, Way, WAYY more intimate than that sunset capitol place (and I have seen them their twice before).
The Brew does seem to rotate singers as they need, but the core band never changes. The young man currently on vocals did a smashing job. They even introduced a beautiful young lady to do a couple of Celia Cruz songs and those were astounding too. It seems if you take a moment to go support local Austin music, this would be another band to add to your list, support, and enjoy!
