We tried House of Blues last month and it was wonderful, we had a 5pm ressie and the place was very quiet and pleasant and the food was outstanding.
You can purchase gift certificates for them at Restaurant.com, I just bought a $25 certificate for $2, there is a $35 minimum purchase, but you can easily do that.
I also agree about Wolf Gang Puck Express, you get alot of food for the money or CS credit. My mom and I could share the Rotisserie chicken plate and still have food left.
DH and I love Cookes of Dublin, but you have a Ragland Road ressie, so I don't think I would do both. I think we are going to try Ragland Road in Dec for our Anniversary.
T-Rex is also a great option, even just Dh and I enjoyed it and we don't have children
