Back center orchestra seats if you can. Balcony seats are still great - try getting something towards the middle. If you're really pushing your luck, try the lottery 2 hours before a show.
So I am a fat guy and never been to a musical, but I have dropped 120lbs so far this year, but still not enough to fit in theaters, but the people here were amazing, got me a ticket and a comfy chair.
Make sure you kids jump off your seats at the end of the show and be your own dancing queen! And give a shout out to Pepper. I hear he's a pretty fly guy!
Parked on Grove and walked over to ONCE. Lovely show but afterwards, came back to smashed windows and vandalized cars including my own. Be careful - and take BART to the theater.
just take the bart to the theatre because the bart is right in front of the theatre. and the last bart leaves at 1230 so you have plenty of time. go and see it before its gone sept 5, 2010!
