Ahh, you missed Jeffrey's in your assement. relsqui
and I have been pondering this.
Jeffry's has a generally intolerant staff. We were nearly kicked out of there for playing Egyptian Rat Screw one evening. We were the only customers in the place. Also, I believe the seating is all booths, so you can't merely pull tables together.
Santa Cruz Diner has three negatives. One is that the seating is all booths. The other is that the service has been awful there in our experience. Lastly, we have no idea how they'll react 8)
Denny's is probably a pretty safe bet. I've set foot in there twice in around five years. It is, I think, the worst food option of any of the four pretty easily. They might have tables in there which would make it a viable option. They're probably shell shocked enough to let us have run of the place. The only other downside is that it's off the beaten path, so it would be difficult to get to by bus (for anyone at the university).
So I guess the thing to do is to call up a manager, tell them we're loud and of unpredictable size (from 2 to 25 with a high frequency in the 6 to 10 person range), show up late and stay late, and ask if they'd be willing to accept us.
Are you up for it?
