Unfortunately, I think Las Tablas tends to have nice locations-- the one on west Irving Park, just past Milwaukee, is very handsome, and as I noted the other day, they're building a new one on Lincoln that also looks like it will be quite nice-- but I find them the least interesting, most blanded-down-to-a-gringo-comfort-level of the local South American meat places. I guess that means they work as a next step for people who've been eating at meat on swords places, and they're not bad by any means, but for food I'd sure pick El Llano before Las Tablas.
