Why does no one answer the phone. Does the restaurant no take reservations?

Yes, they take reservations

They do take reservations but I've had trouble with the phone as well. When they are not open there is no one to pick up the phone. I can't remember if for some reason I had to dial a 1 before their phone number. I know occasionally there are phone numbers that I have to dial 1 first.

Yes, they certainly do take reservations.
