Fried Oyster Omelette at Seng Thor Coffee Shop (17 April 2011)
Penang Fried Oyster Omelette also known as Oh2 Cien1

(檳城蠔煎) is an oyster omelette dish often available at many hawker stalls and coffee shops in Penang. The omelette is made of a mixture of egg and starch to give it a gooey consistency. The best Penang fried oyster omelette uses fresh, succulent oyster, the bigger the better. Garnished with coriander or parsley, the omelette is served with a dip made of chilli sauce and garlic paste.
The Fried Oyster at Lebuhraya Jelutong Hawker Centre (6 October 2012)

The fried oyster at the Lebuhraya Jelutong Hawker Center, along Lebuhraya Jelutong, near the Jelutong Post Office, is one of my favourites. The stall used to be by the roadside, but disappeared for a while. Then later on I discover that it has moved into the food court itself. I like this one because the price is reasonable while the oysters are quite big and succulent.

Oyster Omelette, Kuta Bali Cafe, Paya Terubong (16 September 2012)

The oyster omelette at Kuta Bali Cafe is a big too wet. Also, there's more starch and egg than oyster. It's my one and only try there.
The fried oyster of Maga Restaurant, Perak Road (28 April 2013)

The fried oyster at Maga Restaurant at the junction of Perak Road and Van Praagh Road is quite good. I like the crispy edges of this omelette.
