First and foremost, be prepared to wait. This is a VERY popular location and even at mid-afternoon times it's busy.
With that said, I had never heard of Texas Roadhouse before a few months ago, but even so, I've been about 4 times since my initial visit. The portion sizes are huge, flavorful, and very reasonably priced. I'll go here for dinner and have enough leftovers for lunch the next day. Plus the yeast rolls with cinnamon butter are fantastic!
The only downfall of this location is service. I've had some fantastic waiters and waitresses, great attitude and excellent suggestions, but this location seems understaffed. Tables often stay dirty for a while and even though my waiter/waitress is running around constantly, my drink goes empty or I need something with my food order and no one is around to assist. This is a busy location and I don't expect someone to hover over me, however, 20 minutes between check-ins is a bit much.
This food and atmosphere will continue to bring me back here. And while I've never had absolutely poor service here, it's a bit frustrating to need something during a meal and not being able to ask for assistance for quite some time. The wait staff always ends up apologizing for not being around; saying they are swamped with tables. This is preventable from the correct actions from management.
