McDonald's is a convenient and familiar spot for a quick bite. The staff are always friendly, and the food is consistently good, with the quarter pounder with cheese being a popular choice. While there have been some minor issues with orders, the staff work to resolve them efficiently. Sometimes, orders containing fries or drinks may not match the request, such as salted fries when no salt is chosen or sweetened tea instead of unsweetened. The curbside pickup through the app is usually smooth and accurate, with food often arriving fresh, although occasionally there are delays or app malfunctions. The bathrooms could use some attention to cleanliness and maintenance, but overall, the staff are polite and helpful. Despite these minor issues, McDonald's remains a reliable option for a quick and satisfying meal.
