You'll need to provide the date, time, location, and number of people in your party. There is a fee for reservations, which varies based on the size of the picnic area. Shall I assist you with finding the reservation website?

Q: How is CityHub different from Google?
A: CityHub offers a more personalized, interactive, and efficient experience compared to using a search engine like Google. While Google is a powerful tool for general information searching, CityHub offers a more specialized, user-friendly, and efficient experience tailored specifically for navigating San Francisco's city services and resources.
- Conversational Interface:
CityHub provides a natural, dialogue-based interface that allows users to ask questions and receive responses in a conversational manner. This makes it easier for users to find the information they need without having to sift through search results and web pages. - Personalized Guidance:
CityHub can provide step-by-step instructions, recommendations, and context-specific advice based on the user's individual needs and questions. This level of personalization is difficult to achieve with a generic search engine. - Curated Knowledge Base:
CityHub's knowledge base is specifically curated for San Francisco city services and resources, ensuring that users receive accurate, relevant, and up-to-date information. With Google, users may have to navigate through multiple websites to find the information they need. - Efficient Information Retrieval:
By leveraging advanced language models and knowledge graphs, CityHub can quickly understand the user's intent and provide concise, targeted responses. This saves users time and effort compared to manually searching through Google results. - Interactive Follow-up:
