I don't know anything about the food, but I do know that Thursday night dueling pianos is a blast- the two guys play the same songs every week, but when you're out with good friends you can sign Piano Man every week at the top of your lungs and have a great time.
Plus, happy hour is certainly worth it- it's hardly ever busy (plus it's such a big place), so there's always somewhere to sit, along with $2 taps and rails- 4-7pm, Monday thru Friday= quite the deal!
