It can be a challenge to find a really good khao mok gai (chicken biryani) in Bangkok, but this gem of a restaurant (opposite the French Embassy's parking lot off Charoenkrung Road) comes shining through. Home Cuisine specializes in biryani, and its mutton is perhaps even better than its chicken, and both are served with pickled eggplant and a side dish of sweet yogurt sauce. There are plenty of Thai dishes on the menu, but stick with the biryani. Tell taxi drivers to come in via Soi 40 to get here. It's a 15-minute walk from the Saphan Taksin BTS station.
