Food:
Atlantis Buffet is currently THE BEST in the area.
For good Mexican, Beto's next to Saint Marys on 5th street downtown. Mi Casa Too on 4th is also good as is El Borracho on Virginia.
Mels in the Sands has the best burgers in town, unless your idea of a great burger involves 12oz of grease and wading through crowds of Oakland denizens.
For BBQ, The Oakland Style BBQ joint on Wells cannot be beat.
Local Micro Brew and food: Great Basin Brewery in Sparks, and Silver Peak in DT Reno are good spots. Both have AWESOME beer.
There are some good Sushi spots like Sushi Pier II and in the Atlantis.
India Kebab and Curry has an all you can eat Buffet for like 7.99.
We have some great food out here.
Guns/Sporting goods:
Honestly, it is OK. Bizarre Guns on Oddie is better now that it is under new management, and they have some cool toys. Silver State Arms is OK. Scheels in Sparks is a sight to behold unto itself. Cabelas is fun to visit and get a buffalo burger. Sportsmans Warehouse is in town as well. We have a place called the Gun Trader, but it is the joke around town. If they don't carry it, it is because it is "x". (insert BS claim, like "AK's Jam too much, Mini14's are more reliable.")
Outdoors here is great. Lake Tahoe, Ski Resorts, hiking, shooting, golf etc.
Hit the NV Home Town Forum and ask to meet at the snack bar at the gun show... bring ding-dongs.
