I don't think it's necessary most weekdays unless you are on a tight schedule. Went once with a party of 6 though and made reservations for a larger table. Another time we made reservations for the a table in a more private, quieter room in the back.
Yes, they take reservations. But, the place is large enough where you probably don't need it on a weekday.
