Cumulus is a restaurant in Hanoi's Old Town that serves bun cha and Vietnamese home-style dishes. The bun cha comes with charcoal-grilled meat and pork patties, and fried pork spring rolls and grilled shrimp are also available to order. Rice and noodles are refilled multiple times on request, and side dishes such as soup, tofu, and egg dishes come at no extra charge. Portions are large enough that two people ordering only bun cha and spring rolls can still leave food behind.
