I've always been a fan of Capriotti's and still think that they have some of the best cheese steaks in Las Vegas. This particular Cap is located in North Las Vegas in the Home Depot shopping center. It's a small restuarant with limited tables/chairs inside and a few more outside.
Cap sells their sandwiches in 3 sizes; 9 inch, 12 inch, and their monster 20 inch. I have friends that recommend the Bobbi (turkey and cranberry) and their Capastrami (their pastrami swiss). I am told both these sandwiches are really good. However, I've yet to try either. I've only tried two different subs here; they're steak/cheese and chicken/cheese. Both meats are thinly sliced, seasoned, and coated in melted cheese. I usually have both sandwiches plain so that I can savor the meats more. You can't go wrong with either sandwich. Simply state, both are delicious.
Service is not bad at all and really depends on how busy they are. Between 11:30 AM and 1 PM, this place can be a madhouse. Cap is little more pricey compared to say
Subway, but the food here is much better.
