I had just moved to Arizona a few months ago and have been to this Texas Roadhouse quite a few times. Excellent food, really great prices. Honestly, I'm surprised they weren't more expensive. Their prices are similar to Applebee's but with better quality food.
Only once was the service slow but you could tell they were short staffed because this guy was running all over his section he was charge of. Gave him a good tip because I felt so bad for him.
The bread rolls and butter they give you to start with.. ugh. Do not eat those delicious things if you're not starving. The first time, I was already full by the time my dinner plate arrived.
As far as the wait goes, I've only had to wait up twenty minutes at most. Call ahead and the wait will be less when you arrive.
