When I lived in Summerlin I use to go here after hiking at Red Rock on the weekends. Red Velvet Cafe was always a great ending to a great day. The vegan taco salad is surprisingly good. Thinking about it you won't think so, but you just will have to try it to believe me. :) You can't beat their Red Velvet cupcake either. I love it when they're hot. The carrot cake/cookie sandwich is great too.
Finally a place that named themselves after something they serve and that dish is ACTUALLY worth naming the restaurant after. That sadly doesn't happened often.
Try Red Velvet Cake! You feel like your cheating but you're not, and that feeling can sometimes be priceless!
