http://www.citysearch.com - I like how this site is designed as well. The Venue Detail page is important here because LocalSear.ch needs to have many of those fields and details contained on CitySearch.com
http://www.localsear.ch - this is an existing site we have that you can use for inspiration on how to model the pages.
Homepage - Important to show businesses on the homepage. The Category selection is also very important (being able to switch from Restaurants to any other category. I love the navigation of Yelp.
Venue Listings / Results page - Venue listings need to be displayed in a concise manner but still allowing for text like the review, rating, address, etc. The map on the right side is important to show where the venues specifically are.
Venue Detail page - Please mimic much of the design of Citysearch.com's venue page (in terms of content and data) and look at Yelp's as well.
