Recommendations on POS systems for restaurants

Hello everyone! I'm looking to install POS systems in my restaurant to streamline our online ordering process. We want to use the system for taking orders, managing inventory, and tracking sales. Our goal is to improve efficiency and provide a better experience for our customers. I’m particularly interested in systems that integrate well with delivery apps and offer good customer support. Does anyone have recommendations or experiences they can share? Any advice on what to look for in a good POS system?
