I really liked Roberto's but this is the end. We would go to the one on Sunset in Henderson every week. About 2 months ago they changed the staff. The guy that appeared to be in charge was a jerk yelling at the other staff. I ordered Chili Colorado special when I got home I found it was a box of boiled meat. They forgot the Colorado sauce. Last strike so we switched to the one on S Las Vegas Blvd. It seems the staff issues are common at all locations. I order Chili Colorado, Chicken Quesadilla and a breakfast burrito. The cashier and the female cook were going at it with dirty looks and I do understand enough Spanish to know what they were saying to each other. Again there was a problem with the Chili Colorado. The male cook obviously did not want to do it, so he started in on the cashier. I went outside so as not to have to watch the reality tv unfolding in the kitchen. 10 min later my order was up so I grabbed it and hit the door. When i got home it all looked good but the Chili Colorado had a very strong chemical taste almost like soap. The Quesadilla was water logged and slimy from the not draining the chicken. The tortillas were burnt black and smelled of charcoal. The only thing they didn't murder was the burrito. I'm done with Roberto's just hoping I don't get food poisoning for dessert.
