Love the Rhythm Room! I saw Grand Archives there this week and it is the perfect little venue to see any band. Any seat is a good one. The bar is big so you never have to wait to long to get a cocktail.
The only thing I would like is that you could take your drinks out to the patio. With the admission of the 18+ crowd they have to confine the booze to one side and it's not the smoking side. I guess only once vice at a time.
