Skull Creek has an outdoor bar with high tops that you can seat yourself (though in crowded times I am sure it is full as well) They have the full menu, the hostess told me.
As I've mentioned in my review for Skull Creek, if you somehow arrive without call-ahead seating (shame, shame) and have a 1-2 hour wait, you can use the high-tops outside on first come-first served basis.....and the best way to do that is to approach a table that appears almost finished, and ask if they will allow you to have their table when they're finished.......you may wish to buy them a drink or something for helping you (just a thought).
Arriving early will surely help, too, but we are way too busy during the day to alter our dinner plans to a 5 o'clock start. In the summer, it can be too hot outside for that. 30 minutes before sunset is my favorite time, or either anytime after 6:45 if you don't like sunsets, imho.
Again, please, avail yourself of the concierge's call-ahead seating...they do this for Marriott, and you'll only have a 10-15 min wait max. And when you are headed to your table and hear them tell everyone else "2-hr wait", you'll be happy.
Call the concierge early in the day!!!!! There are only a few call-ahead seatings allotted!!!!
AND, use the valet parking, for 2 bucks you can drive right to the front door---it's worth it.
