I used to go to the old location, but as far as concert tickets go, this is the place to come. Always. Soundscapes is great but sometimes they will sell out a lot faster than RT. A few years ago, I needed an extra Regina Spektor ticket for a friend, and I scored. 15 minutes before the show, and they were done selling at the venue.
I've found the staff to be nice and helpful in general, and the record collection is always worth a browse.
