I have been going to Panna II for 13 years now and intend to keep going. My wife and kids love it, too. We tend to visit during off-peak hours, although we do occasionally go on a Friday or Saturday night when the place gets packed. The prices are absurdly cheap, but even if I won the lottery, I would still continue to go. The food may not be up for any awards, but it's still pretty good curry house fare. Service is fast, and yes, at peak times, the wait staff will do their best to manage you out quickly so that they can sit the next table from the line of people outside. Look, at these prices, I don't think you should expect to spend two hours in deep conversation while you run up a $15 check for you and your dining partner. The profit margins at this place are razor thin, so eat up, enjoy the vibe, and get out!
Pros: Prices, The vibe
