Reserve a Seat

I saw a tarpaulin poster for a concert of sorts at Eastwood with a note that said something like "Reserve a seat to the theater." It's with the use of to that this entry is concerned with.

The correct expression really is "reserve a seat for the show." There's no need to use "theater" because it's assumed that whoever is watching will be in the theater. It's like saying, "reserve seats for the basketball game." If you want to use "theater," you can say, "call the theater to reserve seats for the show."

I'm watching a classical music concert with my buddy Maisa in January. We're already reserving seats for the show, I think.
