Where to go for Lamb in Hanoi?

Dung Rau Lau De Quan (87 Lang Ha, Ba Dinh): There are already excellent posts on where to get good 'pho', the national noodle soup of Vietnam, on the blogosphere (ie., see stickyrice). Here, I introduce a somewhat different dining experience - the lamb grill eatery. A popular such eatery with locals as well as my co-workers is on Lang Ha (steps away from the Fortuna Hotel). It is almost always crowded during dinner time, esp. during the winter, and for good reasons - the food is outstanding and cheap. But don't expect comfort. Expect to crouch on red/blue plastic stools around a small metal table. And, sweating profusely. Suggested menu:

Grilled Lamb Meat: comes in generous portions with the usual assortment of herbs, condiment (salt, pepper, lime, chili and pepper) and sauces. For a hassle free experience, have the establishment grill the meat for you - it's simpler. Price: 25,000VND (2.5USD).

Lamb Sausage: ground sheepmeats and fat mixed with assorted herbs and spices in non-synthetic (I assume) casing. Calorie count unknown, but truly tasty.

Sheep Foot: try the sheep foot, a delicacy which is of limited availablity. If you come late (ie., after 7:00pm), they will likely be sold out. Personally, I'm not crazy about foot as food as there isn't much meat on the feet. Price: 8,000-15,000VND (.50-.90USD) depending on size.

Lamb Hotpot: finish with a hearty hotpot of lamb meat, tofu, sheep liver, bean curd skin, assorted vegetables and noodles that diners cook in a broth flavored with Chinese herbal medicine. Price: 60,000-70,000VND (4USD) 2 sizes with the larger version featured above.

Price: Should come to around 50,000VND (3USD) - 100,000VND (6USD) per person (including one or two beers) if eating as a group and sharing a hotpot.

Lastly: (1) go when its cooler (Nov. to Feb.) to avoid grilling and stewing in the heat. It really matters for a good dining experience; (2) go with a group of people so you can try different dishes and share the hotpot; and, (3) dine early. Don't be part of the 'second wave' as (a) the dishes are cleaner; and, (b) you can probably sample the sheep foot=)
