Flame MRB and Restaurant.com

Does anybody know if I can use an MRB coupon and a restaurant.com gift certificate at the same time at the Flame?

I have a $50 (must spend $100) restaurant.com gift certificate. If anybody who has used their MRB coupon for the Flame and would like to go again and meet there, I would happily share this certificate. I will be going Friday September 9th right at 5:00 p.m..

They've usually been very good about allowing you to use multiple coupons, certificates, etc., especially if there are a bunch of people at the table. Sometimes they'll split things into three or four checks, so all the offers can be used.

However, the last time they were there (Aug. 2), the server (who I think was new) wouldn't allow it at all; just one coupon/offer per table. Hopefully he was an outlier.
