The restaurant is told to handle the OpenTable check basically as they handle a traveller's cheque. No problem using it to apply for any portion of the bill, in my experience.

We have a number of 1,000 points restaurants in the Sacramento (California) area - several of them actually very good restaurants, like Bidwell Street Bistro in Folsom and Paul Martin's American Bistro in Roseville. And a few OpenTable restos around here are also part of the Rewards Network program, nothing like double dipping and using a newspaper, online or Entertainment coupon in combination!

I enjoy getting my fifty dollar OpenTabel checks and love spending them. ^
