Summary

Pull Saizeriya Singapore's current menu (Grand, Lunch, Kids) and 44-outlet directory as structured data via deterministic static-URL GETs — the site exposes no JSON API, but its three versioned PDF endpoints plus /menu/ HTML index function as one.

Saizeriya Singapore Menu Data — Use the Website Like an API

Purpose

Pull Saizeriya Singapore's current menu (Grand, Lunch, Kids) and outlet directory as structured data, without scripted browsing. The site is a thin static-HTML shell whose only machine-readable surface is three versioned PDF files plus one static restaurant-search page — the optimal "API" is a GET against deterministic URLs whose filenames the HTML index publishes. Read-only.

When to Use

  • Daily / weekly snapshots of the Saizeriya SG menu to detect new items, price changes, or seasonal swaps.
  • Bulk extraction of the 44 outlet directory (name, address, phone) for store-locator features.
  • Anywhere you'd otherwise scrape saizeriya.com.sg HTML — there is no JS-rendered data path, so cheap HTTP GETs beat any browser-driven approach.

Workflow

The site is a flat, static Apache site. There is no JSON / GraphQL / XHR endpoint — every probe to /api/*, /sitemap.xml, /robots.txt, /menu.json, /data/menu.json returns 404 (verified 2026-05-19). The "API" is two GETs:

  1. GET /menu/ — HTML index that surfaces the current three PDF filenames in <a href="/pdf/...pdf"> tags. Filenames are versioned by date (see Site-Specific Gotchas) so they rotate when the menu refreshes; always parse the HTML index first rather than hard-coding filenames.
  2. GET /pdf/{filename}.pdf — the canonical machine-readable menu. Three variants link from /menu/:
    • Grand Menu — /pdf/GrandMenu{YYYYMM}S_single.pdf (current: GrandMenu202603S_single.pdf, 8.84 MB, last-modified 2026-03-23).
    • Lunch Menu — /pdf/lunch_{YYYYMM}.pdf (current: lunch_202511.pdf, ~1.0 MB raw / ~750 KB decoded).
    • Kids Menu — /pdf/kids{YYYYMM}S.pdf (current: kids202603S.pdf, ~480 KB raw / ~360 KB decoded).

A residential proxy is not required — bare HTTPS GETs return 200 OK on every endpoint. The site has no anti-bot, no cookies, no auth, no rate-limit headers. Browser-driven scraping pays a ~50× cost premium and surfaces zero data the static fetch doesn't.

Step-by-step (API path)

  1. Discover current PDF filenames — GET https://www.saizeriya.com.sg/menu/, parse <a href="/pdf/(...)\.pdf"> to get the three current filenames. The <h3> next to each anchor tags it GRAND MENU / LUNCH MENU / KIDS MENU. The HTML response is small (~11 KB), text/html, no JS rendering required.

  2. Fetch each PDF:

    GET https://www.saizeriya.com.sg/pdf/{filename}.pdf

    Response is application/pdf with Accept-Ranges: bytes and Last-Modified (e.g. Mon, 23 Mar 2026 04:14:02 GMT for the Grand Menu). Use If-Modified-Since: {Last-Modified} for cheap freshness polling — the menu refreshes on a multi-month cadence (2025-11 lunch, 2026-03 grand+kids).

    The Grand Menu PDF is 8.84 MB. Two practical retrieval paths if your fetch transport caps response size (e.g. Browserbase Fetch API's 1 MB cap returns 502 The response body exceeded the maximum allowed size of 1MB):

    • HTTP Range — send Range: bytes=0-1048575, then iterate Range: bytes={n}-{n+1048575} and concatenate. Server returns 206 Partial Content with Content-Range. Verified 2026-05-19 via in-browser fetch() against the live PDF.
    • In-browser fetch() — open any same-origin page (/menu/ works), run await fetch('/pdf/GrandMenu202603S_single.pdf').then(r => r.arrayBuffer()), then exfiltrate the bytes (e.g. base64 over CDP or a data: URL). Bypasses the transport cap because the response is consumed inside the browser process.

  3. Extract text from each PDF. Recommended: Node + pdf-parse (new PDFParse({ data: buf }).getText()); Python + pypdf / pdfplumber works equally well. Each PDF is single-page with menu items in English + Simplified Chinese plus prices in the form S$X.XX nett. Sample (Kids Menu):

    Chicken Wing 5pcs  S$4.90 nett  鸡翅5只
Double Potato      S$3.90 nett  双份薯角
Corn Cream Soup    S$2.90 nett  玉米奶油浓汤
Kid's Meal         S$5.90 nett  儿童套餐
Italian Pudding    S$3.90 nett  意式奶冻
Oreo Cheese Cake   S$3.90 nett  奥利奥芝士蛋糕
Free Flow Drink for Kids (Age 4-12)  S$1.50 nett per pax

    Item structure repeats: {English Name} S${price} nett {Chinese Name}. The header line (date stamp like 2026.03) and footer disclaimer (Presentation of food may differ...) are predictable boilerplate — strip them before parsing.

  4. (Optional) Outlet directory — GET https://www.saizeriya.com.sg/search/ returns ~60 KB of static HTML with 44 outlets. Each outlet is a <div class="bubbleInfo"> containing:

    <div class="popup_m pop2-{slug}"><h6>{Outlet Name}</h6></div>
<div class="popup pop1-{slug}"><p>
  <span class="header01">{Outlet Name}</span><br>
  Address:<br>
  {Street address}, Singapore {postal code}</br>
  Tel: {phone}<br>
  Fax: {phone}<br>
</p></div>

    Outlets are grouped by region anchor (#central, #east, #north, #northEast, #west). A short slug (lcsc, csm, nex, etc.) appears in both pop1-* and pop2-* class names — usable as a stable outlet ID.

Browser fallback

Only useful when (a) your transport blocks PDF downloads entirely or (b) you specifically need the rendered visual layout. Open https://www.saizeriya.com.sg/menu/ in any Chromium session, snapshot the three PDF anchor refs, click into each one. The browser's built-in PDF viewer renders the menu inline. There is no benefit over GET + pdf-parse for data extraction — the Chromium PDF viewer is non-introspectable from the snapshot tree (PDF.js renders into a <canvas>/embed that yields no a11y refs), so you cannot extract menu text from the browser DOM. Use the browser only to download the bytes (via in-page fetch()) when your HTTP transport has a body-size cap.

Site-Specific Gotchas

  • Filenames are date-stamped and rotate — the current pattern is {type}{YYYYMM}[S]_[suffix].pdf. Observed today: Grand GrandMenu202603S_single.pdf (2026-03), Lunch lunch_202511.pdf (2025-11), Kids kids202603S.pdf (2026-03). The S suffix appears on Grand + Kids but not Lunch — assume it's a Singapore-region tag, not a guaranteed pattern. Always parse /menu/ HTML for the current filenames; never hard-code. Hard-coded URLs will silently 404 the next time the marketing team refreshes the menu.
  • Grand Menu exceeds 1 MB (currently 8.84 MB). Transports with a small response cap (notably the Browserbase Fetch API, capped at 1 MB and returning 502 The response body exceeded the maximum allowed size of 1MB) cannot pull it in one shot. Apache serves Accept-Ranges: bytes so use Range: requests, or pull the bytes inside a browser session via in-page fetch(). Lunch and Kids PDFs fit under 1 MB and can use any transport.
  • No sitemap, no robots.txt, no JSON endpoints. Confirmed 404 on /robots.txt, /sitemap.xml, /sitemap_index.xml, /api/menu, /menu.json, /data/menu.json (2026-05-19). Do not waste turns probing for a JSON API — it does not exist.
  • No anti-bot / no auth. Plain HTTPS GET returns 200 OK on every endpoint. --proxies / --verified flags on the Browserbase session are unnecessary cost for this site; bare fetch is fine.
  • html declares lang="ja" despite serving English — the site was forked from Saizeriya Japan and the lang attribute was never updated. Don't rely on lang to detect locale; trust the .sg domain instead.
  • Multiple GA/GTM tags — pages embed three Google Analytics IDs (UA-65535147-1, UA-134913146-1, UA-140695686-1) but no data of interest. They do not gate content and can be ignored.
  • Currency / GST — every menu page footer states "All prices are nett (inclusive of GST, No service charge)" and the homepage repeats GST Inclusive & No service charge. Treat all extracted prices as final consumer-paid SGD; no separate tax math needed.
  • Operating hours are global, not per-outlet. Footer states 11:00 am – 10:00 pm (Last Order 09:30 pm). Individual outlets may close earlier (esp. CNY) — confirm with the outlet via the Tel: in the /search/ block before relying on these hours.
  • PDFs are flat single pages. Each of the three is pages=1 per pdf-parse. Don't paginate — iterate items via regex on the extracted text (S\$\d+\.\d{2}\s*nett is a reliable price anchor).
  • Chinese translations are co-located. Items in the PDF text stream alternate English line → price line → Chinese line. When the layout uses centered/spaced glyphs (e.g. KID'S ME NU), tabs and stray whitespace appear mid-word — normalize with s/\s+/ /g before keyword matching.
  • Apache Content-Security-Policy: upgrade-insecure-requests is the only security header; no HSTS, no CORS preflight. Cross-origin fetch() from https://www.saizeriya.com.sg/ is unrestricted to its own origin, which is what the in-browser large-PDF retrieval trick relies on.
