Yeah, I know Baskin Robbins is gone. But you can take away the name... the sign still looks like Baskin Robbins, so it's still an easily recognizable landmark for his sister-in-law to use if she's on the bus.
I would definitely say stick with Yojimbo's, Mission Bay, or Rapid Transit. I've had service from all three, and they're all great.
Oh- Yojimbo's has a bonus, because he has used bikes, so if she's on a budget, she can perhaps find something used.
