Just bring some attitude if its dinner time on a weekend. If your not a regular, and have reservations, you could still end up waiting an hour+ as "regulars" without reservations walk in and are seated. Don't even get me started about Valentines Day occurances! Grrrrrr!
At least breakfast works wonders. They open at 9:30AM on Sunday's.

Yum!
