Do you need reservations?

Need. No.....recommend, yes

We recently went on a Friday night without reservations at 5pm and were seated in minutes. When in doubt, get the reservations.

During any major holidays or with a large table need I would suggest it, otherwise if it was really full on like say a Saturday night, the wait isn't terribly long, you can always wait at the bar and have a drink, or order and eat dinner right at the bar.

No ... but I would call ahead just in case they are crowded

For your convenience always call for a reservation. The staff is very accommodating.

I recommend reservations anytime you go. I have never been there without them.
