A while ago I bought 2 Restaurant.com vouchers for GIO cafe on AVE P in BKLYN. I was told they no longer accept the vouchers so I called Restaurant.com and they sent me exchange gift certificates. Now, how do I use them at the discounted rates e.g. if I want to use the $4 instead of $10 special, how do I use the code. Can anyone walk me through this. I hear that Dougie's also doesn't accept them anymore. I would try Mendy's in BKLYN. Thanks. Chaya
