I've done my searches and read the threads; there isn't much. I'm interested in Grubstake because of its admittedly quite small Portuguese "menu." We haven't had a bona-fide Portuguese place in Chicago for some number of years, so anything is better than nothing (or is it?) and Iluna for its Basque (again, nothing in Chicago). The general take, as I read the mostly older reviews, is that Iluna can be loud and the food uneven. Grubstake, to the extent there's much in the way of reviews, seems okay and possibly even pretty good, but not worth a special trip.
Can anyone offer much in the way of recent substantive experience? Thanks!
