We tried to get into Boudro's, but with a two-hour wait, we were encouraged to go to Zinc, their sister restaurant. While not on the Riverwalk, it was a short walk away.
We ordered the tableside guacamole, which was good, but perhaps not the best I've ever had. I had the steak and frites, which was a good size and tasted delicious. I also thought it was reasonably priced at $22. I also had a mojito to go with it -- very nicely done.
