I noticed a couple of interesting places on North Lamar today but wasn't able to check them out. Upon doing a search, I found two brief mentions of El Tacolote. One referred to it as "real Mexican food" like you'd find at Arandas (http://www.chowhound.com/topics/427011 ); the other, by the same poster, named their gorditas and al pastor as favorite dishes. La Parrilla Guadalajara is mentioned in this thread (http://www.chowhound.com/topics/355647 ), but the poster hadn't tried the food at that time.
I also saw what looked like a new Mexican-char-grilled-chicken restaurant on northbound Lamar, just south of the 183 underpass. Maybe near Meadowlark or Thurmond? The south-bound traffic was so bad that I couldn't take note of the name. Honestly, I don't know how those of you who work up north deal with it.
I don't get to north Austin very often. When I do, I usually go for Chinese or Vietnamese food. If any 'hounds could share specific details about their (recent) experiences at any of these places—dishes sampled, specialties, comparisons to similar restaurants in town—that would really help me prioritize my chow trips. Who knows? Maybe some tantalizing descriptions of their food would persuade other 'hounds to try these places, too.
