We had high hopes for Yardbird. We took some friends here when we stayed at the Venetian.
First, they get extra points for having gluten-free fried chicken. It took a little longer than the rest of the meal but it was GF and really was on par with other fried chicken. My friend was delighted.
As for the rest of the meal - it was just kind of meh. My wife got the chicken and waffles and it was alright but nothing you couldn't find somewhere else (for less cash). My shrimp and grits was downright awful. The grits were overcooked and the shrimp were not flavored well. The fourth guest had the hamburger and had the same comments - nothing special.
For the price of admission you can find better spots in the Venetian. I'd skip Yardbird.
