Hi P.!
Here are a few more options:
Del Frisco's Double Eagle Steak House
5251 Spring Valley Rd, Dallas, TX 75240-3007 • ###-###-####
(there used to be one on Beltline Road in Addison too, but I don't know if it's still there or not)
Nick & Sam's
3008 Maple Ave, Dallas, TX 75201 • ###-###-####
Pappas Brothers Steakhouse
10477 Lombardy Ln, Dallas, TX 75220 • ###-###-####
I've been to Del Frisco's and Pappas Brothers, both very very nice, but not Nick & Sam's, although they too were on the list of the top 10 steakhouses in Dallas that I found on the web.
I've been to Del Frisco's, Ruth's Chris, Pappas Brothers, Fogo De Chao, Bob's Steak and Chophouse, Kirby's, Dunston's, The Keg, Texas Land And Cattle and Outback, of the ones that have been mentioned already, and I'd say my favorite of these would be Ruth's Chris. But to be honest, whenever I want a steak, I usually go to The Macaroni Grill as I love their Tuscan Ribeye, and it doesn't cost $45 plus sides. :o)
I know it's for a special occasion though so I hope you find someplace your husband will love!
