Upscale in Grapevine
Dino's Steak and Claw House is the restaurant I couldn't remember above. Main Street. Mixed (star) reviews covering the spectrum.
(BB & Luigi's) Vineyard Steakhouse with adjoining Skybar - rooftop patio. Texan Trail @ NW Hyw (SH26) Very close proximity to The Gaylord. Excellent (star) reviews
I haven't been to either so can't offer specifics.
Here is a link to a recent post for the same general area, but unfortunately, the "guide" links are obsolete due to the Dallas Morning News completely revamping the guidelive website. However, if you google any of the restaurants listed, I believe they should all have their own website available. Depending on traffic lights, Trulucks and Brio are probably about 15-20 min away, everything else is about 5-10.
You will not see Silver Fox noted here as it is my least favorite (won't go back) of all the upper end steak houses in the area, but it is in GV as well. It's owned by the same group that now owns III Forks, but managed with a completely different agenda - much more relaxed (as is Grapevine in general and that's fine), but in my opinion, the steaks, for the price, are just not on par with alternatives.
For Italian, I heard good things about Ferrari's Italian Villa - for both lunch and dinner, although I haven't been.
There is also a relatively new restaurant on Main (Grapevine) but don't recall the name. Maybe someone else can help out. I believe it features steak and fish. It's pretty much mid-way between the railroad tracks and NW Hwy, on the west side of Main.
Cocoa has some nice options for the Southlake area. Trulucks is a very good chain as is Brio. Trulucks does a fantastic job on their steaks (a great char flavor unlike any other) and of course the food of the gods, Stone Crabs (I like the mustard sauce).
As far as Grapevine proper, Bobs is an excellent choice, and is an easy going upscale choice in my estimation. I am not sure I would classify this as a chain, but I suppose it would be the proper term. The Grapevine store is actually owned by Steve Hartnett, not Bob (who btw is in a bit of legal wrangling over a business deal gone sour). I have been to this location, and it is top notch with supreme service and even better steaks.
I like going to Tolbert's just down Main a bit, but I haven't dined there. Rather drank heavily and enjoyed the numerous bands. Kathleen, the namesakes daughter, can often be found scurrying about in her signature bandanna, giving first rate attention to her clientele. As a chili aficionado, I need to try her red out.
The Old Hickory is also very good and located in the effervescent Gaylord Texan complex. Try the foie gras topped bone-in fillet, yum. This might be the best steakhouse in the area, and most upscale (see: Fromager on staff).
