System Requirements Document for restuarant

1. Introduction

Shyam Mishthan Vatika requires a visually striking public business website that promotes its restaurant, sweets, snacks, and chaat offering to customers in Lucknow, Uttar Pradesh, India.

The website will present the business as a festive, appetite-led neighbourhood destination for families, evening chaat visitors, sweet buyers, festival shoppers, wedding buyers, students, and people seeking gift boxes. It will help visitors discover the business, browse the complete menu card with food imagery, understand its location, and contact the business through phone, WhatsApp, contact form, or map directions.

The current deliverable is a production-ready, responsive website implemented in one standalone HTML file with all HTML, CSS, JavaScript, responsive behaviour, animations, metadata, structured data, and interaction logic included. CDN-hosted libraries, Google Fonts, Unsplash image URLs, and the Google Maps embed are permitted external resources.

2. System Overview

Current Delivery

The system is a public, anonymous-access website for:

• Business Name: SHYAM MISHTHAN VATIKA
• Business Category: Restaurant / Sweets / Snacks / Chaat
• Address: Lucknow - Sultanpur Rd, Arjunganj, Lucknow, Uttar Pradesh 226002
• Phone Number: 099563 91007
• Target Location: Lucknow, Uttar Pradesh, India

The public website will provide:

• A branded landing experience with a navigation bar, hero, business story, testimonials, FAQs, statistics, and conversion prompts.
• A complete menu destination that presents every item contained in the authoritative menu-card attachment.
• An individual AI-generated or food-specific image for every menu item.
• A contact destination with a validated contact form, click-to-call phone link, WhatsApp action, business address, Google Maps embed, and footer.
• Responsive viewing and interaction from 320px wide screens through 1600px and larger displays.
• Branded loading, scroll, hover, parallax, count-up, navigation, and mobile-menu interactions.

Actors

The active human actors are:

• Restaurant Visitor
• Business Owner

External and technical actors include:

• Google Maps, which provides the embedded location map.
• WhatsApp, which receives outbound chat requests.
• The visitor’s phone application, which receives click-to-call actions.
• CDN providers for GSAP, ScrollTrigger, Lenis, Google Fonts, Unsplash-hosted images, and other permitted external resources.

Exclusions

The current website does not include:

• Online ordering.
• Shopping cart functionality.
• Payment processing.
• Reservation management.
• Customer login or account management.
• Owner dashboard or content-management system.
• Role-based permissions.
• Delivery tracking.
• Inventory management.
• Administrative menu editing.
• Unverified menu items, prices, descriptions, or dietary claims not present in the supplied menu-card content.

2a. Product Interpretation and Delivery Boundary

The product is a public-facing promotional website rather than a transactional restaurant platform. Visitors can review the business, explore the menu, contact Shyam Mishthan Vatika, call the provided number, start WhatsApp communication, and use Google Maps for directions.

The website is anonymous and does not require visitors to create accounts, sign in, or provide credentials before browsing any current destination.

The contact form is a visitor-facing inquiry interaction. It must validate submitted values before presenting an acknowledgement state. The destination or service that ultimately receives the form submission is not specified by the source material; therefore, the static implementation may provide client-side validation and a truthful submitted-state demonstration without claiming a backend delivery channel.

The current scope includes a complete menu display based on the attached menu card. However, the menu-card item text, category structure, prices, and item details are not available in the supplied requirement evidence. The final implementation must use the actual attached menu-card content as the authoritative source and must not invent food items, prices, ingredients, availability, or descriptions where they cannot be verified.

2b. Source Content Inventory

The attached menu card is an authoritative content source and feature reference.

Verified requirements from the menu-card directive:

• The website must include the whole menu card.
• Every food item written in the menu card must be listed.
• Every listed menu item must have its own accompanying AI-generated food image.
• Menu items must be grouped according to the categories verified from the supplied menu card.
• The menu content must not be reduced to broad category summaries when authoritative item-level content is available.
• The website must not substitute invented menu facts where the attached menu card is the authoritative source.

The menu-card attachment itself, including its food-item names, prices, descriptions, category headings, and any dietary or serving information, is not present in the available evidence. These facts remain required source content for implementation once the attachment is accessible.
