Rooftop at Alma

Can anyone suggest the wait I might expect for a table on the rooftop deck at Alma? It will probably be three or four people on a Saturday night when the weather is nice (of course). I don't think we'd have a problem going as early as 6:00 to avoid a long wait, but that might not work on a beautiful Saturday.

Anyone have any tips?

Also, it is the kind of place where you can stay at your table and have a few drinks after your meal, or do they hurry you along to seat the next diners? I realize that this question is completely counter to the issue of waiting because the longer we stay, the longer someone else waits :?

Any advice is appreciated!
