I actually received this email from my colleague so thought of sharing it with you all. I have not tried most of it so not sure how true is this. The author's name was also not in the email so I can't add it in here. Hope you find this useful and the tips are right ;-)
Best place to eat in KL
1. CHOW KOAY TIEW - Jalan Imbi : the corner restaurant which is on the same row with Sakura, and opposite of Honda Kah Motor.
2. WANTAN MEE/KARI MEE - End of old Subang airport road, in the Subang New Village Town Centre.
3. TAPIOCA NOODLES& VEGETABLES - Old Klang Road : a shack which is nestled behind a chinese primary school, after the market and the post office (which would be on your left).
4. KARI MEE (LEMAK) - SS1, PJ : Alisan Restaurant (2nd shop from corner), facing the Lorenzo Furniture Shop.
5. ROAST DUCK RICE - Seapark : Sunrise Coffee Shop
6. PRAWN MEE/KARIMEE/CHEE CHEONG FUN - Seapark : Coffee Shop near old Paramount Theatre.
7. PAN MEE - Along Jalan Tuanku Abdul Rahman behind Kah Motors.
8. HOKKIEN MEE - Petaling Street opposite Hong Leong Bank
9. CHAR SIEW RICE - Jalan Tung Shin
10. NASI KANDAR - Kayu Nasi Kandar Restaurant in Taipan, Subang with a branch in SS2 a coffee shop formerly known as Cheow Yang
11. Teh Tarik & roti - Taman Desa next to the water tank
12. If money is not an issue - Madam Kwan (Nasi Lemak & curry fish head)
13. Little Penang (chow Koay Tiew & Prawn mee)
14. Bak kut teh - Jalan Imbi behind hong leong bank
15. Satay - Naan Corner in Ampang, in between International School and RSPCA, called Nur Satay.
16. Banana Leaf - Kannas in SS2, behind Lisa De Inn hotel.
17. Nasi Lemak - Suzi corner, next to Ampang city (used to be called Kerris)
18. Won Ton Mien/Char Siew - Jln Sungai Besi; on the way to PLUS. Only open at 7pm-2am, a car repair shop by day.
19. Beef Brisket noodles - Tengkat Tong Shin; runs parallel to Jalan Alor. Stall near the beginning of the road. Open at night till late.
20. Char Siew/Chicken rice - Tengkat Tong Shin; further up the road. Old prewar shop house. This has to be the drop dead unhealthiest piece of anything you can insert in your mouth in KL? but to die for. Chicken is strictly as filler to make sure you don't get a heart attack overdosing on char siew.
21. Fish balls - Tengkat Tong Shin; a little further up the road from char siew. Stall inside a coffee shop. This guy is good, look at the amount of people he employs to helpout!
22. Hokkien mee (KL style - thick, black, yummy (sounds kinky) Petaling Street; at the intersection opposite Hong Leong Bank. Full of porcine goodness. Still the gold standard of Hokkien mee.
23. Seafood noodles - Segambut; near Auto Bavaria. A big bowl full of noodles and assorted mussels, prawns, cuttlefish, fish etc. for reasonable price. Pick of soup, clear, tom yam, curry. Forget the rest, or for the curry. Soya bean with cincau not bad. Avoid on Sunday mornings.You will wait for an hour. Fried Chicken Rice (only on Weds and Sat)!! There is a branch now open in SS2 Chow Yang, called Restoran Yu Ai with yellow sign board, just a few doors away from Kayu Nasi Kandar.
24. Ploughman's Lunch ? Finnegan's Seri Hartamas. A big plate filled with a pot of pate, slices of ham, pickle, onion, chunks of cheese, a slab of butter, 4 hunks of bread. If you are EXTREMELY hungry, this one's for you.
25. Chef's salad - Flagz; behind Souled Out. This salad is as all salads should be - crunchy FRESH veggies, and the dressing is to diefor. Easily the best salad in town. And I don't even like salad. Beer is the ! freshest in town too, great bite.
26. Hokkien Mee (Penang style otherwise known as Prawn noodles) Champ's; Jalan Telawi 3, Bangsar Baru. Standard gone down somewhat recently, but still head and shoulders above all others in KL. You'll have to go to Penang to beat this.
27. Char Kway Teow Bukit Damansara; behind Hock Lee supermarket, next to Shell. Corner stall inside coffee shop. Best in KL. The fellow has been frying for longer than I can recall, and he is so good that you may have to wait up to 45 minutes during lunch time. Doesn't use too much oil almost perfect. As above, you'll have to go to Penang to beat this. Other stalls in the same shop not bad.
28. Chicken rice Jalan Gasing; very close to the Federal Highway, same row as Southern Bank 2 shops one in the middle, one in the corner.Can't decide which is superior, but both are very good. Middle one has Ipoh taugeh.
29. Bak Kut Teh Klang, just about anywhere. Hokkien Association off the main highway leading to the heart of Klang is a good place to start for beginners.
30. Dim Sum ? Marriott Hotel. Chinese restaurant here serves northern China style dim sum. Easily best dim sum in town. A little pricey.
31. Fish head off Jalan Sungai Besi; just past Won Ton Mien, turn left right after BP. Three shops clumped together. All look dilapidated but don't worry. Don't know what type of fish they get their heads from, but I suspect fresh water fish. Hot sauce fish head to die for. Extremely reasonable prices.
32. Bak Kut Teh Segambut; go past Auto Bavaria, follow road all the way until you see a Chinese temple on your left. Enter the temple courtyard and you will see a tin shack where they serve bak kut teh. Not quite up there with Klang, but nothing to sneeze at... Go for yam rice rather than white rice. Fried Chicken Rice (only on Weds and Sat)!!
33. Nasi Kandar/Kerabu/Laut Taman Tun; the other end of Secret Recipe in a store on the same block, usually with a van outside. Truly Kelantanese style. Only in the morning though...
34. Seafood ? Pulau Carey; get to Jalan Banting and follow signs to Pulau Carey. Place called Kang Guan, just before the actual bridge onto the island. Cheap!
35. Nasi Lemak TangLin at Lake Gardens, near the Clinic/Hospital. Only open when government depts open.
39. Chicken rice - Bing Restaurant in Sri Rampai. Wait till you drop to eat the chicken rice. Worth it.
