It's hard to find cheap decent fast food along the strip. The Orignial Chicken Tender is together with Nathan's (hot dog) at the food court of Monte Carlo Hotel is a good option.
We needed a quick bite to maintain our schedule while walking around the casino.
I ordered the chicken tenders and fries combo along with lemonade. The food was made to order. Nice, tender, and with a crispy exterior. Great for soaking in the alcohol after a long night. Fries were freshly cut and cooked to perfection.
