Here are two hints.
First try OpenTable.com. You might be surprised. Since V-day is mid-week this year, you might actually find some availability at the last minute. I've used OpenTable multiple times and have never been disappointed.
Couldn't find availability? What if you reserve a hotel room near your fave cafe and get take-away?
Now the big question. Which hotel. I can't solve that problem as easily, but I can give you a list of TV's hotels, motels and inns for you to match with the correct series.
