Found this place on Restaurant.com for our recent Vegas trip. Nice little salad/sandwich/panini shop in a strip mall.
Nothing fancy but everything is prepared for you on order, fresh, toasted hot, simple and not overly salted which we LOVEd.
The owner and crew were very pleasant and came over to check if everything was OK and also to have very friendly conversation (we went in between lunch and dinner time and it was not too busy).
Don't forget the pickle-on-a-stick - The best we've had so far!
