So for the record do I need a Reservation to be seated & can I just walk up in nice jeans,suit blazer Led Zeppelin shirt and get in???

You need a reservation and no need of formal dressed

They prefer reservations eg more than 4 persons, its not a big deal if you are just out by yourself or two people, i have been seated immediately, without reservations.

I think they prefer reservations. Call before just to be safe. Enjoy!

You need a Reservation and must be casual dressed.
