Kobes is a lot of fun! (and great food, too) It's a Japanese Steakhouse where the chef cooks on the table top right in front of you, with lots of fire and entertaining antics. I'm a very fussy eater and thought the food was amazing. While we went to the one in Kissimmee, I believe there is a location in the Crossroads which is SUPER close to SVR.
The Outta Control Dinner Show, on I-Drive, would also make for a fun and memorable dinner. It's maybe 15 minutes from the resort. Tony Brent is fantastic and the food (when we were there about 4 years ago) was pretty decent. Unlimited beer & wine, too.
Capone's is another GREAT choice. So much fun that we've done that dinner 4 times in 2 years. Food is excellent (Italian buffet), the alcohol is unlimited (highly recommend the rum runners!!) and the show is a hoot. Splurge for VIP tickets (an extra $15 pp) and you'll get some fun inclusions (the best seating in the house, free gambling in the upstairs lounge before the show, pre-dinner appetizers, first to the buffet, and a souvenir shot glass). If you're looking for more than just dinner out, and a real "night out", this would be perfect. It's only a 10 minute drive from the resort (on the 192) and super easy to find.
