How many people would actually show up for dinner vs. arrive Saturday morning, though?
Brothers Sushi is not a good option for a 30-person crowd. I don't think I'd want to go there with much more than 10 people. It's a small, intimate little sushi bar.
If we eat in Ventura, I'm down for whatever the group wants. I'm a fan of Macaroni Grill, and they can certainly handle large groups better than most places (I assume, not having been to the Ventura MG but many others), so I'm fine with that if others are. If we're talking about a full 30 person crowd it's going to limit our options considerably, so perhaps we should get a head count.
