there are many good food like bakuteh,bbq fish and fresh seafood

Kuching is beautiful, clean, and generally a pleasure to visit. It is also a great jumping off point for three wonderful parks, Bako, Gannung Gading, and Kubah. Kubah is the closest (although in some ways the hardest to get to) and has the nicest hostels... it's like staying in a country cottage, very beautiful. Bako definitely has the best opportunities to see nature and wild life (at least 3 kinds of monkeys as well as mudskipper fish, monitor lizards, and more!). Gannung Gading is very nice and also well worth a vist. A week plus trip can be a great way to see the city with ample opportunities to visit the wild life of Borneo!
In Kuching, check out the BB Inn, a wonderful place to visit at very cheap (15-25 RM per night for 1 person depending on if you want a dorm or a hostel.). Very close by is a giant neon colored mall with great malaysian food in the food court, and a nice sidewalk cafe on the corner.
In the early evening you get the impression that Kuching rolls up the sidewalks at dusk... but by 11 the night life explodes into a wide array of trendy bars, clubs, and disco's...

KFC is the only place in town with air conditioning!

Look out for cheap seafood restaurants at the edge of the town nearer to the Selangor River. Around the area there are small shops selling sea/river catches and processed fish stuff (fishballs, fish paste and etc). Grab their "ha peng" prawn crackers if you see any. Yummy addictive crackers!

There are no public transport other than the bus. Not very reliable and you have got to wait quite sometime before the next one comes along. You will have better luck if you are driving.

No grand hotels there. Most you will see are cheap motels. Kuala Selangor is not very develop. A fishing village/town.

Look for "yau char queh", a type of deep fried flour bread/pastry in the Setiawan morning market located behind the local food court. Delicious stuff.

Sitiawan is also famous for their "Hock Chiew Peah" aka "Kong Peah". It's a type of Chinese hard bun cooked in a clay oven and stuff with lard and onions. You can only find Hock Chiew Peah around Setiawan and the near by village/towns, and no where else in Malaysia.

Look out for their local dishes as well, the "oh chien" oyster omelet, "ang chio mee sua" red rice wine noodles, and "loh mee" a type of noodles cooked with baby bamboo shoots.

During a hot day, you can also try the "cendol" a type of Indian dessert in front (or near) of a supermarket called Fajar.

There are no classy hotels around the area. 3 Star max. Many cheap inns and motels.

Taxis and local bus for transport. Will work better for you if you have a car.

Setiawan is about 15mins away from Lumut, where the jetty to take a 20mins boat ride to Pangkor Island.

Small town with limited things to do. Fresh and cheap local seafood.

Bus and taxi as transport. But better if you have your own car. No classy hotels, just cheap inns and motels.

Plenty restaurants selling exotic food at night in Gopeng. Fruit fox, terrapin, frogs, snakes and many more.

Limited taxis, and busses are not convinient. Good to have a car.

No other entertainment there. This is more of a 'just passing' town.

This Island is amazing. Spend a few days in Georgetown. This old colonial city is a amazing mix of cultures and there fore there is an incrediable mix of religions, food languages and ambiance. Go during Chinese New Year if you can. The China town "Open House" is amazing but it is hot so take a umbrella. Take covering clothing for temple visits and cover up a little bit if you can as a woman as it is predominantly muslim. Its ok to wear a t-shirt but as a respect thing i wouldn't wander around in short shorts. Compare money deals with the different exchange places as you can wheel and deal if up for it. And for cheap amazing food go to the Red Garden food court.

dining ikan bakar with wonderful landscaping, go to Cerana Restaurant di Cheras (depan plaza Phoenix ). ...

Look for the Saturday night pasar malam near the railway track. Grab your food and just walk opposite the road to the beach area. Lay your picnic cloth and enjoy the food, and the lovely sun set.

Nothing much to do there. There's the ostrich farm hear by which serves superb ostrich burger and satay.

The beach there is not that nice. The sand is not really fine, and the water not clear.

I think the best thing to do is just lazing in the 2 best hotels... Gouman and Avillion.
