If you do a search (using google with the qualifier for lthforum works best, so you would type in "Schmaltz site:www.lthforum.com" without the quotes, works best) you should find detailed posts on all these places with reviews and locations. Those threads will also lead you to other detailed discussions on dining in the western suburbs. You could also just do searches by town.
If you have specific types of places or foods you are looking for, let me know.
