There are lots of places to eat in Frisco.  Nothing unique really .....

Frisco has the American chains like Chilis, Fridays, Bennigans, Applebees, Cruisers, Down Under Pub, Snookies, Hooters, and Irish Rover.  From experience Chilis is usually the best.  Italian choices are Buca de Beppo, Macaroni Grill, and Olive Garden.  Buca is wonderful for large groups b/c the food is served family style.  Great atmospshere for families or dates. 

For steaks you can go to Outback, TX Land and Cattle, or Randy's.  Outback is usually our choice.  Randy's on Main Street is very good too but somewhat pricey. 

Mexican is popular in our household and there are several places to chose from there too.  Christina's, Gloria's, Manny's.  Manny's has a popular buffett on Wednesday nights.  Gloria's has a great patio for happy hour.   

Restaurant/Bars - Snookies, Irish Rover, Down Under.  Snookies has good drink specials.  Decent food.  Down Under for those looking for a date.  They have pool tables as well.  Irish Rover has decent food and a large beer selection.  The place gets real smokey.
