Just an update. Loved Dallas, but my regret is that class took a lot out of me, and the fact is was 105 degrees and extremely hazy out, I did not get to site-see nearly enough, but I would definitely plan to go again.
As for eats, Sunday we got in and by the time we were settled and rested, all we did was find somewhere close, so I have to admit we did a chain (champps) but I will say, the walnut encrusted chicken was excellent. Following night, I wanted to get downtown to eat, so we decided on Primo's Tex-Mex. Very good fajitas. Next night after that, we discovered on the way to the class we were taking there was a fogo de chao. I have been to a few of these, but my travel mate had not, so I was not one to ever pass up initiating someone to fogo! Then for the last night, we were all set to try out Hard 8 bbq, but we had Marshalls bbq for lunch in class, so we were full and bbq'ed out.
Thanks again for the recommendations, and hopefully I can try them on some future visit.
