Just got back from a venture to Sullivan's. I went with the intention of getting their long bone, obvs. -
http://sullivanssteakhouse.com/seattle/menus/dinner - but found out it's restaurant week and they had this deal going for 3 more nights:

I figured I'd do that while it lasted and come back another time for the long bone, but I might've mumped up. When I ordered, she said I could actually get any steak I wanted and they'd bump up the $30 deal accordingly. For some reason, I didn't have the ball to do a long bone as the main course. I went with the regular ribeye which made the whole deal $40.
So, a $10 upcharge for switching to a steak that's $5 more on regular nights according to the linked menu, but on the one at the table it was a $9 difference so it seemed fine. The long bone was also $62 on the menu, not $61. So I don't know how the math would've worked out if I'd subbed in a long bone, or if I'd even have been able to eat everything. The cheesecake was relatively small.
I guess I've got 2 more nights at which I could give it a shot.
But even if you just ordered the regular offerings on that deal at $30 total, not a bad dinnerhack. Lesser eat'rs could even take some to go for a subsequent lunchack.
