What It Is

洪瑞珍 (Hong Rui Zhen) has made the same sandwiches in Taichung since 1946. The product is a thick sandwich on pillowy Taiwanese-style white bread — soft, slightly sweet, with a very tight crumb — filled with combinations of egg salad, ham, tuna, pork floss, or cream cheese. There is no English menu and no table service. You queue at a counter, point at the sample photos, pay, and leave with a paper bag.

The shop is not a chain discovery: it is a single-location original that predates Taiwan's sandwich culture by decades, has not franchised, and has changed the recipe minimally since the 1940s. The bread is baked on-site. The egg salad is made with Japanese-style kewpie mayonnaise. The result is specifically Taiwanese in flavour — not Hong Kong milk bread, not Japanese konbini sandwich, not Western deli.

Where

Address: 中山路196號, Central District, Taichung (中山路196號 near the old station area)
From Taichung Main Station: 10-minute walk south along 中山路.
Note: There are Hong Rui Zhen imitators and similarly-named shops in Taichung; the original is on 中山路 near the old city centre. If the storefront does not say 1946 or 創立民國三十五年, it is a different business.

Hours

Opens approximately 07:00; closes when sold out, typically by 12:00–14:00. Arrival before 09:30 on weekdays avoids the longest queues. Weekend queues begin earlier. The shop does not take pre-orders.

What to Order

The egg salad sandwich (蛋沙拉) is the canonical item — it is what 洪瑞珍 is known for and has the most consistent following. The ham and egg (火腿蛋) is the second choice. A single sandwich runs approximately NTD$45–65. Order two or three for a full breakfast.

  • 蛋沙拉三明治 (egg salad): ~NTD$50
  • 火腿蛋三明治 (ham and egg): ~NTD$50

Pairing With Second Market

洪瑞珍 and 第二市場 are both 10-minute walks from Taichung Main Station and are approximately 10 minutes apart on foot. Combine them into the same morning window: market breakfast (滷肉飯, soup) at 07:00–08:00, 洪瑞珍 sandwiches to carry as a mid-morning snack before the National Museum of Natural Science. The sandwich travels well in its paper bag for 1–2 hours.

Note on scarcity: Sell-out times vary by day and season. If the shutter is half-down or the counter staff are turning people away, the shop is out of stock. There is no second chance on the same day.
