We went to Ruth's Chris Steak House on a Tuesday night during restaurant week. Despite having a reservation, we ended up waiting for 45 minutes. The food was good, but I wouldn't gush about it. I don't care for the way they seem to overcharge for everything. For example, the wait staff cruised by asking if we would like a glass of sparkling water. She poured us a glass and we later discovered we were charged $6.50 for bottled water. Likewise, $3.50 for a small cup of coffee seems pricey.
While the ambiance is nice, it's not a place one would routinely go due to the cost. I can think of 5-6 other restaurants that have food that is just as good or better quality at a lesser costs.
If you do have dinner here, make sure you have enough $$ in your checking account to cover the cost.
