With some casual and upper-casual restaurants feeling the sting of the economy...some are now diving into the 'Happy Hour' pool. Here are some restaurants that will begin offering some great deals to get you in the door. Some of the programs will vary by location...but here are a few restaurants entering the 'game' (list from USAToday):

•Cheesecake Factory. After 31 years, the chain just began to roll out its first Happy Hour. It'll be in most locations by March 18. "We've all been hit by the economy," says Mark Mears, marketing chief. "We have to be sensitive to those with less discretionary income."

The Happy Hour is Monday through Friday from 4 to 6 p.m. in the bar area. Some 16 appetizers are available, and specialty cocktails are $5 each. That includes a margarita (normally $8.95) and Hot Spinach and Cheese Dip (normally $10.50).

•P.F. Chang's. In January, the chain went national with a Happy Hour promo that it had previously tested in parts of Oregon and Arizona. The promo offers drinks and appetizers priced at $3 to $6 from 3 to 6 p.m.

"Our customers have asked about it," says COO Rick Tasman. "People are watching their pennies, and I don't blame them."

•Morton's Steak House. The fine-dining chain rolled out Power Hour in the bar area in 2009. Bar Bites such as sliders fetch $5, and beer is $4. "It allows guests to drink and eat for around $25," says Edie Ames, president.
