Liliana's Restaurant

Food was fine, service was very friendly and attentive. The hostess asked if we had a reservation and implied we should have made one, but luckily we were able to "squeeze into" a dining room that was basically empty besides our party and 3-4 other tables. It never became more than half-full during the hour or two we were there - at least 10-15 tables were empty the entire time - but on the way out we heard the hostess asking a couple to wait 10-15 minutes and telling them they should have made a reservation. Is this to ensure good service with limited staff, or just faking reservations to appear exclusive? Either way, this is a VERY strange way to handle it.
