Yes, Sam's SL will have a roof deck according to the staff, which will be open to the public.  Not sure what they're doing yet, maybe a grill or something of that sort, or cheese & crackers like their wine bar on the main floor...we'll see.
Also, great patio at Bon Soiree, and since their indoor space is so tiny I prefer to only dine there when it's nice outside.  Brunch, dinner...it's all good.  And A Tavola does have a very nice patio, which Brad told me they are overhauling:  a bit bigger and with a working garden which customers can walk through/around.  Sounds great, and I can't wait to have that sage-brown butter gnocchi outside again!
The W Division strip is so crowded with sidewalk seating that you literally have to weave your way down the street from Ashland to Western.  Not that I'm complaining since I live 4 blocks away.

I also agree that the Art Institute 
Garden restaurant is great, with the reflecting pool and overhanging trees.   And let's not forget the outdooriest of them all, 
Oak Street Beachstro!

Homer: Are you saying you're never going to eat any animal again? What about bacon? Ham? Pork chops?
Lisa: Dad, those all come from the same animal.
Homer: Heh heh heh. Ooh, yeah, right, Lisa. A wonderful, magical animal.
